    Tevo Black Widow 3D Printer Review

    In this review, I will take a look at popular Tevo Black Widow 3D printer. In our earlier article, we compared all Tevo models. Here, I will test out this larger volume 3D printer and guide you through an entire process from unboxing, assembly to printing out with various materials.

    The Black Widow is the coolest name for almost anything –  including a 3D printer. Taking from the spider the design of this printer is the coolest printer on the market. I’m not much for bland things and I try to spruce up my things with cool stickers or paint.

    This printer has the coolest heat bed I’ve seen so far. Too bad it gets marked up with molten plastic. There is the option of using glass but I didn’t have time to order a piece and it was too late after my first print anyway.

    The bed is covered with the popular buildtak type surface. Which can be a bad thing. Well, it is for me anyway. Some like it but I find the prints stick to well at times. I did learn a trick but it was too late. My first print was a PLA power supply cover for another printer.

    The print turned out great but stuck so bad it left the first layer or two on the bed. To clean it I had to turn the heat up to 120 and scrape off as much as I could with razor blades.

    So after this, I started to use Hairspray as a separation layer and so far it has been working. It’s too bad because a glass would have kept it nice. I may still order one.

    Black Widow Technical Specification

    The Black widow has a nice look as well as a fair size build volume. So far my experience with consumer level printers has been around a 200X200X200mm build volume. This printer has a 250X362X250mm build volume. Personally, the larger volume was great for cosplay models I print. It means a lot less gluing pieces which never fit together 100%.

    Unboxing

    The packaging of this printer has been the best I have seen for all the printers I have. The boxes are well designed and well laid out. They are not just plain boxes they have nice branding. Each piece to be assembled is clearly marked and accompanied with all screws and parts needed in separate bags. No need to sort one big bag of screws. The extruder comes preassembled and packed separately in foam.

    The one thing that did bother me is there is no included test filament. So if your printer arrives before your filament order you are out of luck for trying your shiny new toy. It wouldn’t cost much to include even 10 meters of PLA.

    SD Card

    Although it’s nice to include the 8GB SD card it comes empty. Every other printer I have reviewed has included the free software as well as STL files and even Pre-sliced Gcode files for test printing. It’s not hard to copy these files although the pre-sliced files could have settings not well for the filament you have.

    Assembly

    My 10-year-old daughter wanted to (and did) help me build my previous Anet E10. We waned together to assemble this one as well. The problem was there isn’t much to assemble there. It does come nearly fully assembled, like the Creality CR-10 and the Anycubic i3 Mega we already reviewed on the blog. It is, however, easier to build it from scratch compared to the Anet A8 for instance.

    So I let her help me build this printer when it arrived. I’m happy to my kids taking interest in the things I do and want to build things with their hands and not just in Minecraft and other games.

    This printer is made with 40X80MM extruded aluminum and building it was fun. It uses proper T-nuts. Assembly when pretty smooth. The included build manual is detailed and informative. But the Cable chain and endstops are missing a lot of detail so I turned to Youtube for the answers. This video was extremely helpful while building it.

    The control box is flimsy acrylic but looks very cool with the included LED strips.

    Print Quality

    As always, I try to test the printing quality by using a different type of filaments. Below are results for each type of printing material I tried.

    PLA

    PLA is the easiest 3D printer material you can print with. But it does require a part cooling fan which this printer is currently lacking. I’m not sure why any printer company today would design a printer without one.

    So my first print being a cover for a power supply of another printer I own was a hard lesson learned. Not because the print turned out badly but because it stuck to the bed as mentioned previously. Even without the fan, this print turned out pretty good. Although it could be better with a fan.

     

    My next print is the very popular Benchmark boat aptly named Benchy. This turned out pretty awesome without a fan. The bow is a large overhang that printed better than any other printer I owned. But it’s not without its flaws. The house and the smokestack has signs of no fan.

    So I added the part cooling fan and it did improve the print but could be better and with a second fan, it probably will.

    I then printed my favorite tolerance test. This test was created by the 3D printer youtuber Makers Muse. He offered the files for free for a limited time. This tests the gaps between parts ranging from 0.05 to 0.5. This printer did ok but not great. The .5, .4, and .3 were movable with no effort. The .2 took a lot of persuading. There was no getting .15 to .05 to move at all.

    Next, I printed something else this printer is missing and although solid they have rough edges from the missing part cooling fan. This is a spool holder. I found a nice top mounted spool holder.

    PLA is not good for parts that need to be in high heat situations like in a Car on summer days or in direct sunlight for long periods of time.

    ABS

    ABS is the opposite of PLA in it doesn’t like part cooling fans and is one of the hardest materials to print with. It takes more heat from both the heated bed and the extruder. It also works best in an enclosure where the heat from the bed and extruder help keep the part from cooling so fast it warps and sometimes pops off the bed. Printing small parts are OK. Large flat parts, on the other hand, warp pretty easily.

    I printed these two auto level sensor mounts so that I can add the auto level in the near future. I believe all printers should have auto level nowadays and the Bltouch is an option for this printer when you purchase it. The mounts came out OK but the top layer seems to be missing in spots. Simple to fix with extra top layers.

    PETG

    If you need parts that can handle the heat of the sun or the heat of the heat of the extruder and you can’t print it in ABS then PETG is the next best thing. It takes higher heat to melt and it doesn’t warp as easy as ABS. One downfall it’s stringy.

    Proper retraction settings can minimize that. I printed a housing for a part cooling fan but I set the extruder temp to low and I had a split that broke the part in two. I glued it back together and going to give it a try to see if PLA prints better.

    Next, I tried a phone case for my daughter’s galaxy S6. It didn’t fit but with the extra heat, the layers stuck well.

     

    Flexible Filament (TPU)

    Flexible filaments (TPU) are amazing and require precise extruder with little to no room for the filament to ooze out of. The extruder is well designed and enables printing flexible material right out of the box, which is great.

    TPU is great for printing things like phone cases although they won’t offer a lot of protection in a fall. They are good for other things like the tires for RC vehicles and squishy toys. I print tires for the Open Formula RC project. https://www.thingiverse.com/thing:2123450

    Software

    Cheap printers always come with free open source software. Cura comes on the SD card but there are others you can download such as Slic3r and Craftware. But if you want the best it will cost you $150 USD. That is called Simplify3D. It great because you can customize your support structure and it prints well.

    Upgrades and Modifications

    This printer doesn’t need much in the way of upgrades. Aside from the part cooling fan and spool holder.

    Here are a few other upgrades that may be of interest to you if you own one.

    If you want to be creative and find the ways to improve Tevo Black Widow, you can either try to design your own parts and modify printers performance, or you can browse through the bunch of free upgrades Tevo users already added on Thingiverse.

    Pros, cons, and evaluation

    PROS

    • This printer is heavy and that makes fewer artifacts from frame movements.
    • The 5:1 gears and all metal hotend make this extruder precise great for lots of materials.
    • Extruder aluminum frame uses wheels instead of bearing on smooth rods. Rod bends easy and bearings wear out.
    • Easy to build. This printer is much simpler than most of the other kits I have built.
    • Large build volume. The volume on this printer makes it easier to print larger things so you have less gluing of pieces and that in turn makes parts stronger.
    • The bed is run through an external mosfet and can handle the current it needs for such a large bed.
    • The bed is insulated and heats up pretty quickly.
    • Gunner style power button. The button has a cover you have to flip up which is very cool.
    • The black widow branding is a nice look for geeks like myself.

    CONS

    • Acrylic housing for the electronics. Feels like it could break easily.
    • No part cooling fan. With the popularity of PLA all printers should have a part cooling fan. Especially one without an enclosure.
    • No spool holder. Hard to print without a spool holder. You have to make a makeshift one until you can print one. I had one laying around from another printer.

    Evaluation

    Please understand that these ratings are just a personal opinion of the author. They are not comparable with other ratings or printers on our site since we have several reviewers. However, these ratings should be a guideline to understanding overall printer performance the author experienced.

    PRINT QUALITY: 7/10

    This printer can be 8 or 9 in print quality with a proper fan.

    BUILD QUALITY: 10/10

    This printer is built well and solid. I love not having to screw it down to prevent artifacts from vibrations.

    USER INTERFACE AND NAVIGATION: 5/10

    I give the interface and navigation a 50 because you can’t-do fine control for movement because each click of the dial moves 3-4 positions. So if you want to move the axis .1mm you can’t unless you control it over USB.

    VALUE FOR THE MONEY: 9/10

    The current cost of this printer is $389.99. That is a pretty good deal for the build volume and quality of this printer.

    FINAL JUDGMENT: 8:/10

    This is a nice printer and I recommend it to anyone on a budget that needs a reliable printer with a large build volume.

    Where to buy Tevo Black Widow Printer?

    We recommend several retailers where you can get this printer if you decided it’s the right choice for yourself.

  • An honest review of controversial Anet E10 3D Printer

    An honest review of controversial Anet E10 3D Printer

    When Anet announced their latest printer, Anet E10, it caused an uproar in the 3D printing community. Many people got in an uproar over the fact that it seems to be modeled after the beloved Creality CR-10 and they took offense to that. Which is strange because they didn’t have the same reaction when the Tronxy X3 was released.

    Maybe it’s because Anet wanted to spruce up the E10 with the plastic trim which I love the look, to be honest. The E10 is green (my favorite) and the CR10 is orange (ugly in my opinion).

    The YouTuber Press Reset did a “review” video where he called it the CR10 Killer and trashed it without even trying it out. And his fan base followed suit. Luckily others with in the community kept a clear head and gave it a fair review. Which is what you will get from me. Preston went on about silly things like the printer having printed parts. What printer doesn’t have printed parts these days? That is what the RepRap project is all about.

    Anet E10 Technical Specification

    The specifications of this printer aren’t that bad. Great for an entry level printer. The build volume is a good size and won’t take up to much space. If you need a large build volume then this printer isn’t right for you. Although it is larger than the average entry level printer which is typically 220X220X220. The E10 has a volume of 220X270X300.

    [go_pricing id=”anet_e10″]

    Unboxing

    The Anet company does pack their printers well I’ll give them that. But the E10 could have the bed more secure. The E10 was mostly pre-assembled so unboxing was a breeze. It comes out in three pieces and has a small box with the accessories in it.

    The company seems to be learning from the community as it goes. But I use that term loosely. For instance. When I bought my Anet A8 over a year ago the printer came with very little in the way of tools. Assembly tools and that is it. Then when I received the A6 and A3 they included a pair of side cutters to trim filament from the printed parts.

    Now, most other printer company’s have been doing this for a while and some also include a putty knife for removing prints from the bed. With the E10 however they included the putty knife but didn’t include the side cutters. I for one would have preferred the cutters.

    One more thing they included which most people like is the 3M print surface which is similar to Buildtak. This stuff sticks the prints well. Too well in my opinion. I prefer glass myself. This stuff stuck to the print and put a tiny hole so I just removed it.

    SD Card files

    The SD card comes with the typical things included on the Anet printers. It includes the Cura and Repetier Host software. Also includes the typical sample STL and G-code files, Instruction video and PDF files. The SD is 16GB which is plenty of space to keep lots of files to print. I do suggest you archive them as you go because flicking through them to find the one you want to print can take a while if you have too many. Also, the file name is truncated after so many characters.

    I do suggest you archive them as you go because flicking through them to find the one you want to print can take a while if you have too many.

    Assembly

    Assembling the E10 was pretty straight forward since it comes mostly assembled. The previous printer I reviewed (AnyCubic Kossel) my middle daughter helped me with. So I promised my youngest she could help on the next one as she was away for the last. Even though it was mostly she was still eager to help. It went pretty quick.

    You first place the Upper assembly onto the bed assembly and tighten it down and insert the 2 bottom bolts. Then connect the wires. After that you insert the hotend and tighten it down. Last you bolt on the hotend cover, insert the bowden tube and that’s it. The bowden tube is a tube that guides the filament from the extruder to the hotend. Well in a perfect world that would be it anyway. More on that in the pros and cons.

    Print Quality

    Over all this printer prints very well. Aside from a few hiccups, most prints came out better than I expected.

    PLA

    PLA prints well on most machines and this one is no different.  The first thing I printed was the included Beymax character and that didn’t go so well. The extruder fan is powerful and cooled the hotend to the point it wouldn’t extrude so I only got the feet.

    To fix this I had to put tape over most of the fan to prevent it from cooling it too much. I found this to be a common problem with the other reviewers of this printer. The included filament was so small I couldn’t reprint it because there wasn’t enough left over.

    Instead, I printed the lovable benchmark test Benchy. This little boat tests the printer in many ways and I got to say it came out great. A bit stringy but that could be the retraction settings as well as the cheap filament.

    Next, I printed the included Chinese chess piece that is on the SD card. It turned out OK but nothing special. And to finish the included PLA I printed the Box that is included on the SD card also. This was a great print but not hard to do as it’s rectangular and simple. This is the print the 3M stuck to and put a hole.

    So switch to black PLA I wanted to test the printers tolerances with the model created by the Youtuber Makers Muse. This basically tests gaps in prints at .5, .4, .3, .2, .15, .1 and .05.

    I started the print and went to bed. The next day I found that it didn’t even pass the .5 which is very bad. Upon closer inspection, I noticed the bottom was very warped. I’m betting that letting it cool gradually on the bed is what caused this. I found that very interesting.

    So I reprinted it and this time was there to remove it. This time the tolerance worked all the way down to .2 which is the best I have seen from an Anet and is pretty good. I also noticed a bit of warping on this one too so I wonder if it could do even better. Tolerances are important if you want to print gears or hinges.

    PETG

    PETG is a filament similar to PLA but stronger and doesn’t warp in the sun like PLA because of its higher printing temperature. It is very stringy and in my case wraps. At least the blue roll does. So much so that the nozzle knocked it off the bed.

    The second PETG print didn’t warp and came out beautifully. It is a storm trooper helmet cracked open showing a skull inside. I have been meaning to print that for a while and I’m glad it turned out so well.

    Flexible Filament

    TPU is the flexible filament I have and it’s a cool green color. I have been wanting to make the Open RC formula one car for some time. And each printer I try I attempt to print a tire for the car. Thanks to the E10s great extruder design I now have all 4 tires. The design of the extruder puts very little space between the gear and assembly. See image extruder below.

    The tire came out great. The top looks like it has holes but it doesn’t. The filament is clear and hard to see.

    Anet seems to have learned to use these extruder assemblies recently because It isn’t on any of their other printers I have tried.

    ABS

    ABS is very hard to print with and without an enclosure there isn’t much sense in wasting your filament. I tried to do an ABS benchie and it failed measurably. It warps easy and doesn’t stick. This is partly due to no enclosure and part from the bed not getting close to 90 deg. The bed should be at 100 or 110. But because the power supply was replaced (More on that soon) it took over 30 minutes to get to 85.

    Software

    Cheap printers always come with free open source software. Cura comes on the SD card but there are other you can download such as Slic3r and Craftware. But if you want the best it will cost you $150 USD. That is called Simplify3D. It great because you can customize your support structure and it prints well.

    E10 upgrades and modifications

    As this is a new printer there are no printable upgrades for this printer yet. I’m sure you can use or modify part from other printers using 20X20 extrusions but I didn’t look.

    But there is one hardware upgrade I recommend for ANY printer with a heated bed. That is the  MOSFET. This should be included with a printer with this bed size and I don’t know why it isn’t. The Creality CR10 comes with one but their bed size is bigger and defiantly needs one for the current it draws. They are cheap and there is no excuse.

    Valuation, pros and cons

    PROS

    • Print Quality
    • Extruded Aluminum frame
    • Larger build volume
    • Enclosed electronics
    • Proper wire shielding
    • Dual Z rods
    • Nice LCD display
    • Looks cool
    • T-Nuts
    • Spare parts

    Pros, what can I say? Well, this printer prints very well. Better than any Anet printer I have tried to date. The aluminum makes better axis then smooth rods and bearings. They do use the good T-nuts instead of the flat ones that Anycubic uses on their Delta Kossel’s.

    For the time Anet has included spare parts. Even an extra hotend. Although printed they do have nice endcaps on the extruded aluminum which is a nice touch. And the green stripes are a nice look even if fans of the competition say they are “copying” them.

    CONS

    • Build quality
    • Poor attention to detail
    • The fan cools the hotend to well.
    • Enclosed electronics
    • User interface and Navigation
    • Control knob all dented

    For the cons please see build quality below.

    Summary

    Print Quality

    What can I say here? The print quality is great I can’t argue there. I think it can be better once someone starts designing stuff like a better fan shroud? Not sure that is what it’s called. The current one blows on one side and is probably the reason for the stringing in PLA.

    Build Quality

    I know I didn’t list many cons but I’m going to go into detail here. The build quality for this printer is NOT good at all. It feels very rushed to market. Here are a few minor issues that I encountered but a person new to 3D printing may not be able to get past.

    • The Z motors are facing the wrong way. When they assembled these printers the put the motor wires facing inwards. The bed level knobs hit the wires and will eventually break them. Not a big deal to turn them but why not do that from the start.
    • The Z motor connectors are poor and go loose very easily. This image shows how crooked one of mine was. Again not a big deal but this printer is supposed to be mostly pre-built.

    • My printer came with the bed screws bent quite a bit. Locking it down with zip ties does not work. They need to pack it with foam to stop the bed from moving. Mine had one knob off in the box with a nut I couldn’t find where it came from and a grub screw from one of the Z motor couplers.

     

    • The extruder carriage is loose and can’t be tightened. I tried moving the bolt in the slide hole to the top most position and it didn’t work. Then I thought maybe the belts were pulling it back as I tightened it. So I removed the carriage completely and did it that way. Then slid it back onto the Z axis and put the belts back on. Nope! Still very loose. The video below shows how wiggly it is. But it doesn’t seem to hurt the prints. Just imagine how well it would print with a proper one on it.

    • The control know came dented up. Not a huge deal but come on. They had to see that when they put it on the printer.

    • After I finished the assembly I tried to load filament and give it a try. For the life of me I couldn’t get it to load. So after taking the hotend from the heat-break I noticed it was clogged. Clogged hotend? How come it comes with a brand new hotend that is clogged? I thought it was a one off until someone on YouTube had the same problem. The spare will come in handy if you don’t know what to do. You can use a small allen wrench to push it into the nozzle to be melted when you turn on the heat.
    • My first attempt at homing this printer made me wonder how it ever got through the research and development phase. The bed adjustment knobs get in the way of the pieces that hold the bed smooth rods to the frame. This prevented the bed from hitting the Y axis endstop. I had to switch it to a printed wheel with a nut in it to get it to home. You can see that even the other side rubs onto the knob.
    • Homing the printer wasn’t the only thing stopping me from printing the LCD kept dimming and the printer kept resetting. After a while, it popped and smelled burnt. The fuse blew but didn’t protect the power supply at all. Luckily I had an Anet A8 so I used its power supply for the rest of the review.

    User interface and Navigation

    I give the interface and navigation a 50 because you can’t do fine control for movement because each click of the dial moves 3-4 positions. So if you want to move the axis .1mm you can’t unless you control it over USB.

    Value for the money:

    I wish I could give this more. I feel it was rushed to market to compete with Tronxy and to ride the fame of the Creality CR10.

    Final judgment

    What can I say? It was a bit of a rocky start. And in the end, I am going to have to replace the power supply or tear down the printer for parts.

    Where to buy?

    If you still want to buy this printer you can find it here:

    Conclusion

    I can’t safely recommend this printer and here is why.

    The fact that Anet pre-builds these printers with the power wires inside a metal housing and their very sketchy assembly makes me worried someone is going to get electrocuted. When changing the power supply I checked the wires attached to the board and to the power supply. I found them to not be 100% secure.

    The problem with this is that if the mains voltage wire falls off and touches the housing when someone is touching or holding it they could be killed.

    I know the A8 and A6 have power supplies out in the open but those printers are not targeted at people who may not know any better and if they built the kit they know what they are getting. When they put a sticker over the edge of the case people with not open it to be sure in fear of losing a warranty. And we all know there is no warranty on these cheaper printers.

    If after all this and you still want to buy one or you have the confidence to make sure the wires are good and tight then that’s on you. Just please check before you even plug it in. Like I said it does print extremely well. Just look at this Superman mold.

  • AnyCubic Kossel 3D Printer Review (Pulley Version)

    AnyCubic Kossel 3D Printer Review (Pulley Version)

    Anycubic – a company competing with the low-cost printer companies like Anet and Tronxy. The Kossel is a Delta printer with no heat bed. I thought owning one would be great because I heard they print very well at high speeds.

    I have not found this to be true. I am reviewing the Pulley version. There is also the Linear version which uses linear rails instead of the wheels on the plastic carriage and there is the Linear Plus which has a larger diameter but smaller height. Linear rails are said to be better and it does cost more but I don’t have experience with linear rails, so I don’t know for sure. The pulley version does move smoothly and quietly. If you’re interested in differences between these versions you can check our AnyCubic comparison.

    AnyCubic Kossel Technical Specification

    The table below shows technical specification for AnyCubic Kossel.
    [go_pricing id=”anycubic_kossel_pulley”]

    Unboxing:

    The box isn’t that big and it was packaged well with foam to prevent damage in shipping. Like most kit printers the Anycubic Kossel has many parts. It is intended for people that like to build. It may be intimidating to look at but unlike the Anet series printers, this one comes with a well-detailed manual which has easy to follow instructions.

    SD Card files:

    On the SD card, you will find all the instructions, manuals as well as test files ready to print including 3D Models to try slicing. You will also find the slicer software and the printer firmware. Although it’s best to get the most up to date firmware. Basically, there are no printed guides and a manual, but you have everything to get you started on an SD card.

    Assembly

    I love building kits of almost anything. This is my 3rd kit printer. This time I asked my daughter if she would like to help me build it and she said yes. She was a great helper. The build was straight forward and easy to assemble.

    There were a couple things the company needs to change and if not I recommend anyone ordering this printer to add them to their order. One is proper T slot nuts. The ones the supply only fit one way and that one way isn’t very secure. Even if it raised the cost of the printer it would still be worth it. See figure 1A.

    The second thing they should supply is a cable tie down. These can’t cost more than a fraction of a cent. See figure 1B. This simple tie down can keep the wire from breaking off the heater block and/or thermistor or keep them heater core from pulling out of the block. Which can prevent it from burning something and possibly catching fire.

    Getting the 2020 extrusions to slide onto the plastic corner pieces was a bit tricky but it may be that I did it wrong but with proper T-nuts, it would be much simpler. Other than that the build was pretty straight forward and took about 4 hours with my daughter helping. Normally it would be much faster.

    Before you turn on the printer double or triple check the connections to the motherboard. There is nothing worse than turning on the power and seeing the board burn out because you connected something wrong. I have done this on one of my RAMPS 1.4 boards and one of my Anet boards.

    I also added a label to each of the three stepper motors X Y and Z in order to make it simpler to level.

    The aluminum body of this printer makes it feel well built and could be easily moved while it is printing. Something I wouldn’t try with the acrylic Anet A8 or the A6. Although the cheap T-nuts may make something come off if you did. A buildtak or buildtak type surface included for the glass. More on that later.

    After building the printer you need to update the firmware. There is a download link in the manual. This is done with the Arduino software. The firmware is a version of the open source Marlin firmware. This firmware is popular and used on many printers and most DIY printers. Easy to update but lots to learn if you want to customize it for yourself.

    Print Quality

    Build quality and looks don’t mean anything if the printer doesn’t print well. My first print was the calibration cube. It is used the configure the DELTA_DIAGONAL_ROD. See page 19. Leveling the delta is a bit tricky if you follow the guide book. So I found this Youtube video. I spent more than a day leveling the bed before I found this video. It was very helpful.

    I then printed the popular benchy which is aptly named after the word benchmark. It shows how well your printer prints certain things like lettering, circles, and bridges. The benchy turned out very well and comparable to the more expensive printers. The benchy is printed with the supplied roll of black PLA which doesn’t normally come with the printer. I assume it was supplied for the review.

    After seeing how well it printed I decided to try an upgrade piece (see Upgrade “Top Caps “). This stuck so well to the buildtak surface that it broke trying to remove it. I decided to flip the bed and print with tape on the glass.

    I will be removing the buildtak and tape to print directly onto the glass with hairspray. I like the idea of seeing the mainboard through the glass and will install LED’s to make it look cool.

    PETG

    Without the heated bed the filament types are limited to PLA and PETG. The next prints I printed were bearing mounts for the printer I’m building.

    The PETG is very glossy but strong and stands up to heat as it’s printed at higher temps like ABS. So if you are building a printer you intend to enclose it’s best to use higher temperature filaments to prevent warping.

    Flexible Filament

    I knew my next print would fail but I gave it a try anyway. (eBay link) TPU Sain smart flexible filament. It got wound up on the extruder gears. The flexible filament is difficult to print with. Even at slow speeds.

    PLA

    I went back to PLA to print parts for this printer I found on Thingiverse. See Upgrades and modifications below. I printed top caps to cover the belt pulley wheels for each of the three corners. I also printed motherboard supports. But to install them I need to unplug everything from the board.

    Famous 3D printing Youtuber – Muse created a tolerance test that you can print. It has parts with gaps set at .5, .4, .3, .2, .15, .1 and .05. basically, you try turning each one until you can’t and the smallest number you can turn is your tolerance. Then you know what tolerances to put into your models or which models you can print from the internet. This delta can print with .3 tolerances but it could improve with more setting changes.

    The next print is one I have been meaning to print for a while. It is the Adalinda: The Singing Serpent. This is popular and is included on the Prusa MK2 included SD card. My 16 year old loves it. He is into dragons.

    The last prints are the rod supports. You need springs to use them. The small 10mm springs I used didn’t hold up when printing to the outer parts of the build plate. So I switch them to 14mm springs.

    After attempting the larger lower motor caps I realized the bed isn’t as level as I expected.

    So I went to Thingiverse looking for an auto level sensor. The inductive sensors need a metal bed to work and are typically 12mm in diameter.  The capacitive sensor is 18mm in diameter. I like the glass bed so I had to make my own sensor mount.. The ones that do hold the 18mm ones don’t look like they will hold to the extruder and would be below the nozzle, therefore, aren’t useful on this printer.

    ABS

    ABS is popular because if you print something that has to be out in the sun or hot area it won’t warp without extreme heat. PLA would warp easily. But ABS needs a heated bed and power supply so this printer will not print ABS without that upgrade which you can find on sites like.

    Software

    Cheap printers don’t come with company built software so they include open source software like Cura and Slic3r. They work well and get updated regularly.  I like and use both of these but there are much more. There is also a Prusa edition of Slic3r which they build specifically for the MK2 and their 4 filament add-on.

    AnyCubic Kossel Delta – Upgrades and modifications

    These are some of the printer modifications from the community I would recommend. All of these upgrades can be 3D printer on your Kossel.

    Upgrades I have not made yet

    I haven’t printed any of the following upgrades, but you might find them handy, depending on the printer setup you’re aiming at.

    The base extender is good if you decide to do the heatbed upgrade.

    Holders and Mounts

    The base extender is good if you decide to do the heatbed upgrade.

    Bed Level

    MOSFET upgrade

    A Mosfet is also recommended if you do a heatbed upgrade

    Coolers

    Valuation, pros and cons:

    Print Quality

    Besides the tolerance being so large (.3 isn’t so great) this printer does print well. Most printers now days do and I can only see it getting better as time goes on. Cheaper and better. Which makes me wonder how some companies get away with charging so much.

    Build Quality

    The all aluminum frame makes this printer feel solid and quality. If it wasn’t for the cheap T-nuts I would give it a higher grade.

    User interface and Navigation

    This printer has the same interface as my Anet A6 which is hard to fine tune specific settings or move the axis with precision. That’s because the knob turns the menu values 3-4 at a time.

    Value for the money

    This printer is great value for the money. Even if you have to update the T-nuts yourself this printer is still cheap. And there is a growing Facebook community that is willing to help with any problems you may run into.

    Final judgment

    Pros:

    • Great value for the money. You couldn’t buy the parts for this printer any cheaper then it’s sold for.
    • Solid aluminum build. Nice heavy feel to it.
    • E3D Bowden style extruder. Bowden seems to be what most people in the community seem to update to.
    • Tall build volume. Although it seems to waste space with the rods it does have a taller build volume than most printers.

    Cons:

    • Heated bed is not included (can be purchased separately)
    • Some cheap or not included parts. Again I don’t understand those T-Nuts.
    • Delta style printers are hard to level

    Where to buy AnyCubic Kossel?

    Here are some stores which sell this 3D printer and it’s spare parts or upgrades.

    Anycubic 200mm Delta MK2Y Round Heatbed with Cable
    Anycubic 200mm Delta MK2Y Round Heatbed with Cable
    Amazon.com

    Conclusion

    Delta printers are supposed to print at faster speeds, but I found any faster than 30mm/s and my prints would fail. I will have to do more research into why that is. They are very hard to level so I would recommend an auto level upgrade. I will be doing that after this review.

    It does have a nice build volume if you need to print taller things. So would I recommend this printer?

    Not as a first printer. I think if I had this printer as my first printer it may have turned me off of 3D printing. Well, maybe not because I love it so much.

    I still need to add the auto level and that might change my mind but as stock, I would tell people to start with a cartesian printer first and buy a delta as a second or maybe a 3rd printer.

    I will update this review after I get the auto level working. My opinion may change. As of now, I can only print small items as the y corner of the print is too high and no matter what I do it doesn’t seem to change. This isn’t something someone new to printing should have to struggle with. There are also bed level parts you can print from Thingiverse but I don’t know how well they work and they also take away some of the Z axis height. I’m trying them also.

    If you have already purchased this printer or are up to the challenge or must have a delta printer, then come join our facebook group. So far everyone seems polite and willing to help.

  • Anet A3 Review – Fully Assembled 3D printer

    Anet A3 Review – Fully Assembled 3D printer

    The Anet A3 is a good starter printer for anyone interested in 3D printing who doesn’t have a lot of money and doesn’t want to build a kit.  The A3 comes Pre-Built and cost ~$260 USD at the time of this review.

    While the build volume is only 150mm X 150mm X 150mm it is well-designed, compact and would look right at home on any office desk.  The printer itself is only 317 X 330 X 368.3 mm leaving it the right size for most desks.

    Special Deal : now has special discount for Anet A3. Check the promotion and use coupon AnetA3S to get discount.

    Anet A3 Specification

    Here you can check the technical specs of the A3. If you’re interested in comparison with other Anet printers, check our comparison table.

    [go_pricing id=”anet_a3″]

    Anet A3 unboxing

    The packaging is well done and easy to open. It comes covered in foam and taped to keep it from sliding. The size of the package is 381 X 381 X 431.8 cm.

    After you remove the foam you will find the printer wrapped in plastic wrap to prevent damage during shipping.  This plastic wrap is easy to remove with a pair of scissors.

    Next, take away the plastic and the protective foam inside the printer as well as the box of accessories and any leftover plastic wrap around the extruder.

    What’s inside the box?

    Inside the box you will find :

    • A3 Printer assembled
    • small amount of test filament
    • PTFE bowden tube
    • a power cable
    • side cutters (used for trimming supports off prints)
    • assorted tools like allen wrenches, standard wrench, screwdrivers
    • USB cable
    • USB Micro SD card reader with a MicroSD card
    • Threaded rod for a spool holder
    • 2x printed pieces. One is an X that holds the spool into the printer and the other is a fan for cooling nozzle.

    Do not plug it in at this point. The printer has one more protective layer which is a plastic coating similar to the plastic covering plexiglass when you buy it. It protects the printer from scratches while the company builds it.

    SD Card files

    On the SD card you will find all the instructions,manuals as well as test files ready to print including 3D Models to try slicing. Basically there are no printed guides and a manual, but you have everything to get you started on a SD card.

    • A3 Operation instruction 1.1.pdf
    • Print Quality Troubleshooting Guide-Anet1.0.pdf
    • Software Driver: CH340G for Windows and CH341SER for MAC
    • Software: Cura 14.07 and RepetierHost_1_0_5 (You should just download the newest versions from the internet.)
    • Test models (Needs Slicing): Baymax.stl, Box.stl, Brush barrel.stl, chess.stl, Figure.stl, FU.STL, Pyramid.stl.
    • Test Gcode (Ready to Print): Baymax-1.75mm PLA-A3.gcode, Box-1.75mm PLA-A3.gcode, brush barrel-1.75PLA-A3.gcode, chess-1.75mm PLA-A3.gcode, Figure-1.75mm PLA-A3.gcode, FU-1.75mm PLA-A3.gcode, Pyramid-1.75MM PLA-A3.gcode
    • Mainboard-English.jpg which is a detailed layout of the mainboard.

    Before you turn A3 on

    While I said, even though you don’t have to assemble the printer.

    Bowden PTFE Tube installation

    The first thing is to install the filament holder and bowden tube. Not hard really and they even supply a wrench to install it. To install the filament holder you need to remove one of the bolts on the threaded rod.

    Next, put the rod through a hole in the back of the printer. From the inside you need to screw the nut back onto the rod and tighten it.

    They do only provide one wrench, so if you have one of your own or some pliers I would recommenced tightening from both sides at the same time. Be sure the rod is not sticking to far into the printer that it will impede the movement of the build platform.

    The PTFE Bowden tube helps guide the filament from the roll on the back of the printer to the extruder on the inside of the printer through the opening on the top side. To install this you simply put one end of the the tube into the printed plastic piece sticking out the back of the printer and the other end into the top of the extruder as shown in the picture below.

    Power supply voltage setup

    There are a couple more things to check before you plug the printer in. One and the most important is the power setting on the power supply. This is done through a small cutout on the left side of the printer.

    The switch can be in one of two settings. The first is 110 volt and the other is 220 volt. Here in Canada we use 110 volt so I made sure the switch is to the left in the 110 volt setting. Be aware that you check the voltage in your country carefully, otherwise you can burn the electronics down.

    It is extremely important to choose a proper input voltage by moving the switch to 110V or 220V depending on your location.

    Wiring check

    The other thing you should check is the wiring on the bottom side of the printer. While it looks all neat and tidy one of my display cables had fallen out. At first I turned it on and nothing. I was disappointed thinking I got a bad printer. Luckily, I basically just had to plug them back into their connections.

    Make sure to check if all the cables are properly connected or something got disconnected during the transportation/handling.

    At this point you can plug in the printer and turn on the power.

    Design and build quality

    The printer has an Aluminum coated plastic body which is better than the acrylic body of the previous models. It feels solid and less fragile then the Acrylic A8 and A6. Weighing 20 pounds it feels solid as well.

    The all metal X, Y and Extruder carriages are solid and no chance for breaking, but also adds weight the motors need to move. On printers less weight is better.  The smooth rods are protruding through the frame and the ones that turn are on bearings to help them turn. On the acrylic version the rods are held in place with printed parts leaving more room for error.

    Print quality

    So the design is pretty good and you get a lot for the money but how does it print?

    PLA Test

    Well the first print I did was a new fan shroud. It’s important for PLA to have good part cooling and the stock on only blows on the part from one side of print. The most popular shrouds online are the ones that blow on the prints from all sides.

    I also printed the calibration test. This print has many things that are considered difficult for printers such as thin walls, overhangs bridges and curves. The A3 fared pretty well as evident in the pictures.

    After that I decided to try something I haven’t tried on any of my printers. I printed a rocket in vase mode. Vase mode means it’s printed non stop. Each shell is one row thick. The rocket came out perfect and I’m glad I gave it a try. My daughter loves it.

    Can Anet A3 Print PETG? PETG Test

    My second and third print was using blue PETG. PETG is easy to print like PLA only it is done at higher temperature which means it will stand up to the outside summer temps better. I printed a Y axis belt tension-er and a MOSFET holder for the Anet A6.

    The MOSFET is used to handle current of the Heatbed when you print ABS. I ordered one for the Anet A6 and one for the A8. Since then I have 3 other printers to order them for. A3 included.

    Being pleased with the PETG results, I printed some Batman the toys for myself. The pictures don’t do it justice really. The shine makes it hard to see in pictures.

    You can also take a look at video time-lapse I recorded.

    Trying out the TPU – Flexible filament on A3

    The last thing I wanted to try was flexible filament. TPU is hard to print with because it get wound up on gears. The trick is to print super slow. Like 15-20 mmps. I printed the open RC Formula one tire.

    ABS Test

    ABS. The last filament type I wanted to test was ABS. I don’t recommend printing with ABS unless you remove the bed and solder the wires directly to the bed. The reason for this is that the connectors used are not rated for the current it takes to power the bed at 100°.

    The connector will eventually burn out and stop heating the bed. In extreme cases this could cause a fire.

    I advise you to solder the connectors of the heatbed cable directly to the heatbed if you want to print ABS

    I printer the same Batman bust I printed in PETG. It turned out almost perfect. It is a bit less shinny than the PETG.

    ABS (Left) vs PETG (Right)

    The ABS (Left) curled a bit on the bottom as ABS does without an enclosure.

    That brings me to one of my favorite things about this printer. Because it is basically box shaped it wouldn’t take much to close it in to keep the heat in. Two side panels, one on the front and top would be easy to make. I will do an update with this mod soon.

    ABS shrinks when cooled to fast and makes it hard to print with and sometimes pops it off the build plate.

    That brings me to another great thing about 3D printing and the main reason I got into printing in the first place. Printing trinkets is cool and fun but I mainly got into for Cosplay. The idea I can print endless costumes and props is awesome on so many levels.

    Little did I know there is a massive community that come together and build awesome projects like the Open RC Formula one and even life size BB8 and R2D2 droids.

    With all the model websites now you can find just about anything you need. If that doesn’t work there are plenty of great tutorials on YouTube that will get you started.

    Anet A3 Upgrades and modifications

    There aren’t many printable upgrades for the A3.

    The Mosfet holder which may vary depending on the one you order.

    Bed support. I’m not sure how much this is helping the prints or printer but I printed it anyway.

    Auto level. If you wish to ad auto level to the A3 you would need to update the Firmware to one like SkynetV2.3.2 which is a version Marlin specifically developed for Anet boards. In the file sections of the official Skynet group you will find a sensor mount for the A6 which has the same X carriage as the A3.

    I recommend (eBay link) this auto-level sensor.

    A MOSFET  is used to handle current of the heatbed when you print ABS and other filaments that require the bed to be at high temperatures.

    Buy MOSFET  here |  Link 1Link 2  | (eBay link) Link 3|

    Valuation, pros and cons

    Print Quality: 80/100

    I give this printer an 80 for print quality. It prints just as well as the A6 with no modifications at all. And I’m sure with the proper settings in the slicer you could get up to 90.

    Build Quality: 80/100

    The aluminum body of this printer was a good surprise. It’s block shape makes it strong and right at home on my desk. I think the open sides would be good to cover for printing ABS but with the small build volume it wont print anything big enough to warp to bad.

    User interface and Navigation: 50/100

    I give the interface and navigation a 50 because you can’t do fine control for movement because each click of the dial moves 3-4 positions. So if you want to move the axis .1mm you can’t unless you control it over USB. Also the display could be better if it was angled at 45degs. I will make something up in Fusion 360 and upload it to Thinigivers for anyone who wants it.

    Value for the money: 80/100

    I give this printer a 80 for value. While it doesn’t compete with other desktop printers like the Ultimaker which cost thousands. It does compete with printers such as the Geeetech MeCreator 2 which is a couple of hundred dollars more.

    Final judgment 72/100

    Overall, I give this printer a score of 72. If not for the navigation this printer would compete with printers 3-4 times it’s price point.

    So what are the pros and cons of the Anet A3?

    Pros:

    • Form factor of this printer is great. It looks great and goes well in an office as well as any 2D paper printer.
    • This printer is solid so it feels and looks like it would cost much more than it does.
    • Ease of use. The A3 is so simple to get up and running making it less intimidating for many. Friends and family tell me 3D printing looks fun but without spending lots of money you have to basically build the printer from scratch. Well this printer debunks that. So when I point this out I’m sure some of them will get started with 3D printing.
    • Solid X and Y carriages. The horizontal x carriage makes for a smoother more precise movements.
    • The full graphics display has a nice interface and control. Although as stated before each click move 3-4 digits when changing settings or moving the axis.
    • Filament support. Do to the heat bed and nozzle that reaches 250 there is a wide variety of filaments supported although ABS works for small prints. Large prints would require closing in the enclosure to prevent warping.
    • Tools and USB. The printer comes with the tools needed to repair the printer should you need to fix or replace any parts. It also has a USB SC card reader and a 16GB card for putting files to print on.
    • This printer plays a cool tune at the end of each print. While the loud volume is good if your not in the room when it finishes it痴 pretty loud when you are sitting beside the printer.
    • The electronics are hidden below the printer which is nice to see. Having mains voltage accessible with kids around is not a good idea.
    • Optical Z Endstop. I was surprised to see this as their other printers use switches which seem to be less reliable.

    Cons:

    • The build volume of this printer is pretty small. This is needed to make the printer fit nicely on a desk. Although you can always slice your prints smaller and glue them together which is what may prints need anyway.
    • Manual bed leveling. This day and age most printers have auto bed leveling. The A3 comes stock with a manual level system. This can be fixed by (eBay link) ordering a sensor for under $10 and flashing a community made firmware to the printers motherboard. Very easy to do and lots of info at the Facebook group mentioned above. This tells the printer if the bed is angled in any way and compensates for it.
    • Bed wires not right for the current. The wire on the bed doesn’t handle the current from ABS printing very well. It’s recommended you get a proper MOSFET and solder the wires directly. They are cheap (around $10) and easy to install.
    • Access to put the SD card in and out is out of place and hard to access.

    Where to buy Anet A3?

    Currently there are few places where you can get genuine Anet A3.

    Conclusion:

    So, would recommend the Anet A3 printer? Yes! After owning the A8 and A6 for a while and all the fun I had with the I was impressed at the prints I could accomplish with a Sub $500 printer. The A3 is a nice addition to my collection.

    From the full graphics display to the Horizontal X axis. The A3 will be a good printer for printing smaller items. I wont need to power the larger bed for smaller prints.

    Other than that the A3 has nice touches like branding of the Anet logo on the front as well as the software on the display. The A3 also has a smaller footprint and I will keep it on the desk instead of the table on the other side of the room.

    If you are really strapped for cash then you can’t go wrong with the Anet A8 or Anet A6. But if you can afford the difference then go for the A3 will save you building time. Be warned, 3D printing is an addicting hobby. It should be in all the schools as it will be a common part of most household item.

    This printer would be good for kids to use as the electronics are out of the way. So buy a printer and join us on Facebook for fun and interesting things. Or join the group to help you make the decision.

  • Anet A8 vs A6 – 3D Printer comparison – Which one is better?

    Anet A8 vs A6 – 3D Printer comparison – Which one is better?

    After about a year with the Anet A8 , I learned quite a bit about 3D printing and how 3D printing works.

    The A8 is a kit printer which requires assembly. I really enjoy building these kinds of things so it was the perfect choice for me. That and the price was right. After a year of ups and downs, I wanted to see if the mistakes I made were the fault of myself or the printer.

    When I was offered to review the A6, another kit printer from the same company I jumped at the chance.

    The A6 is the bigger brother/sister of the A8. A well-designed printer which are both modeled after the Prusa i3 printer.  The A6 cost about $50 more than the A8.

    What are the differences between the Anet A8 and the A6 besides the price?

    Well, because I have both I’m in a great position to tell you. Rumor has it that the A8 is being phased out. But that’s OK because the A6 will likely take its place in price. Speaking of price the A8 and 6 have dropped in price over the past year as they become more and more popular.

    While there are tons of similarities, in this article I will focus on differences between Anet A6 and Anet A8. Let’s begin.

    Specification

    [go_pricing id=”a6_vs_a8″]

    Build Volume and Size

    The A6 and 8 have roughly the same build volume while the A8 is a lot bigger in size. The A8 is 500 X 400 X 450 and the A6 being 480 X 400 X 400. This can be both a good and bad thing. While good you have more space on your desk or bench it’s also bad in that it leaves less space to work on. This is especially visible for things like leveling the bed which is a must for any printer without an auto level system. Luckily auto level is easy and cheap to implement.

    Frame Strength

    Because the A8 uses two vertical pieces of Plexiglas with horizontal piece across the top and bottom there is a lot of play and vibrations. When the printer is moving so much in all axis’s it’s leaves what is called artifacts in your prints. They can be waves or ripples. This means you will have a lot more post print processing work to make them look nice.

    The A6 however has a box shape front piece as well as the two vertical pieces that hold the power supply and mainboard. This give much more stability to the printer leaving less artifacts. I recommend bracing both printers to a piece of wood or table top of some sort. This helps with artifacts as well as noise from both printers.

    X axis

    The A6 has a better design for the X axis as it is horizontal and not vertical like the A8. I’m not sure if it makes a ton of difference but it sure feels more stable for the direct drive extruder. The direct drive means the motor which feeds the filament into the hotend is directly mounted onto the X carriage.

    The other type which reduces weight and seems more popular are called a Bowden system. In this system the motor is off to the side and feeds the filament into a Bowden tube which is connected to the hotend. That is good for reducing artifacts produced by the belts flinging the carriage back in forth and also gives you the choice to speed it up with less chance of errors. One down side to the Bowden system is the flexible filaments are harder to print with.

    Heat break (throat)

    The throat AKA heat break is the threaded tube holding the hotend to the X carriage. On the A6 they have a 40mm throat as opposed to the 30mm one on the A8.

    I’m not sure why they are different as they both have direct drive but the 40mm one lets it get closer to the pulley on the motor which helps with printing flexible filaments.

    You could move the A8 one closer but the heater being closer to the motor is probably not a good idea. I’m going to order a bunch of 40mm ones so I can update the A8 as well as keep spares on hand because they are easy to break if you are not careful.

    The display control

    The A6 has a full graphic display with a turn knob for navigation while the A8 has a standard 4 line display and 5 flimsy buttons for navigation. The flimsy buttons can be less so with the button helper mod someone created and shared on the Thingivers website.

    The knob is great but feels less accurate as fine tuning a setting is not possible unless you use a USB connection to a PC to change it. The reason being that each click of the knob moves 2-3 values. So setting 100 steps per mm on a motor would be 101 or 102. I’m not sure if that’s important as it’s very close anyway.

    Another cool thing with the A6 display is it has a tiny speaker that beeps like PC’s use to do which is great because at the end of the print of plays a little tune which is good if you are in a different room. The bad about this is its loud and hard on the head if you are sitting beside it. I don’t know of a way to turn it down.

    Print Quality

    While both the A6 and A8 print very well with a little bit of effort on the users part the A6 prints better in my opinion. The reason for this is because the A6 is generally more stable out of the box. So after printing many items the prints are great on both printers. Although the A8 took longer to get there.

    The A6 has printed more types of filaments out of the box. Filaments like ABS and TPU (Flexible). While stringy these parts printed well. The stringiness is typically filament related but can be fixed or lessened with settings. As seen it prints overhangs, bridges, thin walls, circles, points and small texts very well.

    So both printers print at par with printer costing thousands of dollars. The expensive printer give you things like enclosures looks and better warranties. Warranties are also needed as parts on those printer typically cost more to fix or replace.

    Community Support

    The A6 has more features than the A8 but the A8 is a lot more popular due to price therefore there are many mods that can overcome those short comings.

    Summary

    Whether you buy the A6 or A8 you can’t go wrong. Both printers are great value for the buck. While the company support is lacking there is a huge community willing to help beginners  with any sort of issues they may encounter.

    I recommend the A6 over the A8 because of these differences but the A8 is a lot more popular and has a lot more printable upgrades then the A6. So if you want to tinker and have fun modding and money is very tight then get the A8. If you just want to print cool things and get down to business then get the A6.

    Either way, Happy Printing and welcome to the community!

    Anet A6 Review – Detailed look at cheap 3D printer

    I was introduced to 3D printing 3 years ago at work. They have a 3D printer which cost over $60,000. I was in awe and figured I would never get the chance to own one myself. Then last year I decided to do some research into 3D printing. To my surprise there was actual 3D printers almost within reach of my $500 budget. Those printers were the Anet series printers.

    What can you do with a 3D printer? Well the common thought is they are only good for printing trinkets and not much else. I’m here to say that is not true. They are useful for printing things from household items like replacement knobs to educational props and even custom and affordable prosthetic for amputees.

    What did I want one for? I wanted one for printing cosplay props and costumes and yes – trinkets and toys. So after talking my wife into getting one for the house, I decided to choose the Anet A8 which was the cheapest printer at the time. It’s cheap because it is a kit and you need to assemble it yourself. After using the A8 for a while and learning a lot, I was asked if I would like to review the Anet A6. The A6 is the bigger brother to the A8. And of course I said yes.

    The Anet A6 is an entry level I3 style 3D printer kit the user needs to assemble.

    The Anet A6 is not for everyone. Users who want a printer you buy and start printing right out of the box will not want the A6 or any kind of a kit printer. But kit printers are great for people to learn the inner workings of the printer. This is a good thing because when something goes wrong, and something always does, even on a printer already built, the user will have a better understanding on how to fix it.

    Kit printers can print nice prints right from the start however. I printed this awesome dragon head with no modifications at all.

    Yes prebuilt printers have a warranty but they don’t last forever. The Anet printers have a couple of great Facebook groups that are filled with users that will assist you through almost every issue you may run into. I know this as I am a part of those groups and I like to help when I can.

    The box full of pieces look intimidating when you first open it but don’t fret.

     The kit includes all the tools needed as well as an SD card with the test prints and documentation needed to get your A6 up and running.  The SD card also has the free slicer software with profiles for the printer.

    Although I would download the newest versions from the company offering that software (Usually Cura). As mentioned above the people on the Facebook groups are happy to help with the build and give you advice if you are unsure of any part of the build and as it’s worldwide there is usually someone there available to help you out.

    So what is 3D printing? Well 3D printing is like 2D printing (on paper) only it puts melted plastic down line by line and layer on top of layer. As one layer cools the next layer is being lay-ed down. This is the most common style of 3D printing (Fused deposition modeling (FDM)) but there are other ways that we won’t get into during this review. If you want to know look up SLA and DLP printing.

    In FDM printing the plastic is fed into a heated tip at 1.75mm and 3mm diameter strips rolled onto spools. It works the same way a hot glue-gun works. The printer prints models people create one of a a couple ways. The first being CAD (computer-aided design) software. They are very intimidating to look at and some are very expensive to buy. But there are good free programs like Googles Sketchup to Autodesk 123D that have a lot of free online training from sites like YouTube.

    Another way is to scan objects into the computer with scanning tools. Scanners range in prices from professional ones that cost thousands to Open source community driven ones that use scanners like the Xbox/Windows Kanect. There are also ways to do it with series of images at different angles. I have tried it with the Kinect and it’s very cool.

    There are a lot of sources online for models to print. Basically you download (create) 3D models in .stl file format then slice it into layers and .gcode file format that your printer understands. Places like MyMiniFactory and Thingyverse. That’s all find and dandy, but what if you need something not in one of the usual places?

    Well there are great applications to build 3D models that are not hard to learn, such as Fusion 360 and 123D design and even an online tool called  Thinkercad that is beginner friendly. Any of those tools has many easy to follow tutorials on Youtube. I have been having fun learning Fusion 360.

     

    Anet A6 Specifications

    [go_pricing id=”anet_a6″]

    The A6 has pretty good specifications for a cheaper 3D printer. It is more than enough for the average user.

    Assembling Anet A6

    The A6 took me about 5 hours to build. One of those hours was removing the protective paper from the acrylic pieces. Some people just leave it on, but I think it’s more aesthetically pleasing without it. Some even build the printer with it on then remove it after it’s together. I don’t think that is an advantage either. What I will say is that I found removing it all at once as apposed to removing it as you build did seem faster. I took them off as I went with the A8 and it seemed longer to me. As mentioned above I had no washers with this printer. That wasn’t a problem as I had my own and most places I find leaving them out gives a snuff fit.

    One thing you don’t want to do is over tighten the screws holding acrylic pieces. To much force will snap the part in two. It was a pit faster for me then the average person as I have done this before. As long as you follow the videos and/or the guides you shouldn’t have any trouble assembling the printer. It’s basically turning screws.

    A good thing to do first is to connect all the electronics and test them before you start the build. It will save you hours if there is a problem with say the power supply or motherboard. Just be careful not to heat the hotend past 70 when testing. 40-50 should be enough to know if it works correctly. Same goes for the bed. Put them on something that can handle heat as well. Most people skip this step, it’s up to you.

    Fully assembled Anet A6

    Here are the videos you’ll need to assemble your A6. If you’re having trouble understanding some part of the video, take a look at PDF manual which you can find on an SD card.

    Printing Quality

    My first print from this printer went well. I printed the box from included SD card. This print turned out pretty good for a first print. It was printed with the rill of PLA that came with the printer.

    My first A6 print

    My second print didn’t turn out so well.  It was also printed with the PLA material that came with the printer. The problem here is the most common among FDM printers. It’s what’s known as a nozzle blockage. At least that is what it looks like. Only in this case it was not enough tension on the filament. The spring that comes with the printers are by default not putting enough pressure on the filament for the gear to push the filament into the nozzle.

    This was fixed with a tightening down drive gear (Red) by stretching the spring (Green) a bit. I had to do the same on my A8. Some may think turning up the heat will fix it. And technically it will help by making it easier to push through. But this also makes the filament to hot to cool before the next layer is put on top of it. That can lead to other issues. Best to fix the real problem.

    After fixing that issue I tried reprinting that file only to notice something else. As seen in the image below the rounded parts were miss-shaped.

    After that my prints came out great. I printed three more files provided on the SD card with the included PLA. One is a pencil cup with a bear on it. The second is a puck with chines text.

    The third print I did with the PLA is another popular benchmark test. This print test many different things like overhangs, thin walls, small texts, pointy post and more.

    I also printed this ghost with a different roll of Purple PLA I had laying around the house. It turned out pretty great don’t you think?

    Printing with ABS

    After printing a few successful test prints with the included roll of PLA (Polylactic acid) I decided to test a couple different types of filaments. ABS (Acrylonitrile Butadiene Styrene) is the second most common type of filament next to PLA.

    This little boat is called a Benchy. It’s short for Benchmark. It is used to test different aspects of printing. Things like overhangs (the bow) and bridges like the roof of the boat.

    Testing ABS printing material

    After that I printed an autolevel sensor holder. I will install it after this review.

    Printing with flexible filament

    Another filament and the one I’m excited for is PTU (Polyurethane). PTU is a flexible filament which is great for things like phone cases and tires for RC cars.

    Most common problems

    As an active member of the Facebook group I see common issues with these printers. One being faulty parts. But when you buy one of the cheapest printers on the market you can’t expect top of the line materials. The good news is it’s still cheaper to replace a few faulty parts then buy one if the more expensive $1000+ printers.

    Here is a list of the A6 parts in case you encounter an unfixable problem and need a new part :

    Anet A6 Printable Upgrades

    One of the best things about this printer is the community full of makers who love to make printable upgrades for this printer. Things like the clamps mentioned above to fix circle problem. These are the most common parts people print to update their printers

    Those are a few of the most common printable modifications for the A6 printer. There are many more one the sites mentioned. Simply search the term “Anet A6”.

    Recommended Hardware Upgrades

    Other modifications people do to this printer are not printable but are recommended.

    The first and most important mod is for people who want to print ABS prints. This is called a Mostfet. I don’t know the details but it helps control the high currents going to the heatbed when you run it at 100°C or more. It’s also recommended to change the wires to 12 gauge or stronger. A Mosfet is under $10. To install a mosfet, follow this tutorial.

    Another common upgrade is the an autolevel sensor. The sensor replaces the Z endstop which tells the printer where the nozzle reaches the bed. The sensor probes the bed and tells the printer at what angle it sits so the need to adjust the bed at all 4 corners to the nozzle.

    Buy autolevel sensor

    The next upgrade I recommend depends on the choice in the last. That is a glass bed. Have a 4mm glass cut 22cm X 22cm. It is great for printing on but only some sensors work with glass. The link above tells you which ones will. Go to a local glass or hardware store to buy them. I say them because it’s best to buy 2 because they are cheap and it’s great to have one to print on as the other cools down.

    A common upgrade people in the community update that I don’t have experience with is polymer bearings called Igus bearings.

    Anet A6 Summary

    Print Quality: 8/10

    I give this printer an 80 for print quality. At first build this printer prints at a 60 but after greasing the rods and clamping to a piece of wood the prints went to 80. You can get it to 90 or more by updating some features like the E3D style extruder.

    Build Quality: 7.5/10

    I love this build because it feels solid enough that you could pick it up while printing. I give it 75 because although solid in the end it is acrylic.

    User interface and Navigation: 5/10

    I give the interface and navigation a 50 because you can’t do fine control for movement because each click of the dial moves 3-4 positions. So if you want to move the axis .1mm you can’t unless you control it over USB.

    Value for the money: 9/10

    I give this printer a 90 for value because it is the best printer for this price point. The Tronxy and other knockoffs are cashing in on the success of Anet printers.

    Final judgement 7.5/10

    Overall, I give this printer a score of 75. If not for the navigation and Acrylic frame this printer would compete with printers 3-4 times it’s price point.

    Pros and cons

    So what are the pros and cons of the Anet A6?

    Pros:

    • Solid frame. Even though it’s acrylic the A6 has a solid frame.
    • Solid X carriage. The horizontal x carriage makes for a smoother more precise movements.
    • The full graphics display has a nice interface and control over the little brother A8.
    • 1/2KG roll of filament included. It’s nice to know you have the filament to print with in case the printer arrives before the filament order.
    • Filament support. Doe to the heat bed and nozzle that reaches 250 there is a wide variety of filaments supported although ABS works for small prints. Large prints would require an enclosure to prevent warping.
    • Print Volume. The A6 has a good print volume.
    • Tools and USB. The kit comes with the tools needed to assemble the printer which aren’t to cheap feeling like you get with most furniture that needs assembled. It also has a USB SC card reader and a 16GB card for putting files to print on.
    • This printer plays a cool tune at the end of each print. While the loud volume is good if your not in the room when it finishes it’s pretty loud when you are sitting beside the printer.
    • Long heatbreak aka Throat. This printer has a 40mm heatbreak as compared to the 30mm one on the A8. This means it will be closer to the drive gears making flexible filaments easier to print with.
    • Great online community. Lots of help with problems you may have or a place to show off your prints.

    Cons:

    • Loose screws. While not a huge deal it’s still annoying. The printer has some pre-assembled parts such as the X and Z carriage. These parts have some loose screws so it’s recommended that you check each screw including the tiny screws holding the pulleys onto the stepper motors.
    • The odd time you will come across a broken or missing part. In my case the printer didn’t have any washers. Which isn’t that bad. If a piece of the frame it may be a bit more of a show stopper.
    • Some sub par parts. One of my smooth rods seems to be a bit bigger in diameter than the others. This makes the bearings harder to slide. A bit of grease seems to help until I get a new one ordered.
    • Manual bed leveling. This day and age most printers have auto bed leveling. The A6 comes stock with a manual level system. This can be fixed by ordering a sensor for under $10 and flashing a community made firmware to the printers motherboard. Very easy to do and lots of info at the Facebook group mentioned above. This tells the printer if the bed is angled in any way and compensates for it.
    • Z endstop not adjustable. When the nozzle homes it hits switches at the end of each axis. Because the Z moves when you adjust the bed it’s handy to have a Z endstop that can move and be fine tuned. This is easily rectified with the auto level sensor.
    • Bed wires tot right for the current. The wire on the bed doesn’t handle the current from ABS printing very well. It’s recommended you get a proper Mosfet. Searching Printer Mosfet on Ebay andwill get you the Mosfet recommended for most printers. They are cheap (around $10) and easy to install.

    Where to buy Anet A6?

    Currently there are few places where you can get genuine Anet A6.

    Conclusion

    So, would recommend the Anet A6 printer? Hell yes! After owning the A8 for a year and all the fun I had with it I was impressed ate the prints I could accomplish with a Sub $500 printer. I thought the A6 would be a marginal upgrade. Boy was I wrong. The A6 is a large update from the A8. From the full graphics display to the Horizontal X axis. The A6 printed the flexible PTU and ABS were the A8 struggled or failed completely.

    Other then that the A6 has nice touches the A8 is missing like branding of the Anet logo on the stepper motors and the Spool holder as well as the software on the display. The A6 also has a similar build volume with a smaller footprint. It will be my primary printer from here on out.

    If you are really strapped for cash then you can’t go wrong with the Anet A8. But if you can afford the difference then go for the A6. Be warned, 3D printing is an addicting hobby. It should be in all the schools as it will be a common part of most household item. So buy a printer and join us on Facebook for fun and interesting things. Or join to help you make the decision.
