The future on your desktop

Get involved in the latest and greatest in 3D printing: the MendelMax 2. This next-generation 3D printer is based on Maxbots’ 4 years of RepRap design experience and represents the pinnacle of current 3D printer performance. It’s faster, sleeker, and easier to assemble, all while keeping the price within reach.

Every 3D printer kit starts out in pieces, so that’s where we started too. We completely re-evaluated the design from the ground up, focusing on quality and ease of assembly. That meant completely changing how the printers were manufactured. Switching from printed plastic parts to machined aluminum guaranteed consistency, strength, ease, and elegance.

We also simplified the design to require fewer pieces, less guesswork, and an easier assembly process. The total part count on the MendelMax 2 is about one-half that of its predecessor making the assembly of a MendelMax 2 kit easier than ever. You’ll have your MendelMax 2 up and running in record time.

Thanks to its elegant design, the MendelMax 2 not only has one of the largest print areas of any 3D printer in its class but also one of the smallest footprints. It is also mostly self-contained, making transporting it a breeze. The polished design is unprecedented in its price range. The MendelMax 2 has new color options: the aluminum extrusions are black, and the machined parts are available in a variety of colors. You will get the perfect printer to compliment your personal style.

Hot End Options

The MendelMax 2 is available with a choice of hot end types. The standard hot end is the extremely easy to use and reliable 3mm J-Head from Hot-Ends.com. It is the best choice for beginners and for people who want the easiest, most reliable printing experience. The J-Head can print PLA, ABS, and wide variety of other materials up to a max temperature of about 240C. 

We also offer the new All Metal E3D hot End. The E3D adds a new level of versatility to the printer, allowing you to print high-temp plastics such as nylon and polycarbonate. It is also a great choice for ABS. The E3D does work with PLA, however we do find it is more prone to jamming than the J-Head, so we do not recommend it for people who will primarily print PLA. The E3D can be more complicated and finicky to use so we recommend the J-Head if this is your first 3D printer.

We offer the E3D in both 3mm and 1.75mm. We recommend 3mm for most users. Most people will find it easier and more reliable.

Assembly required. The MendelMax 2 3D Printer is sold as a kit. Depending on your skill level, most people will be able to assemble their printer in about 8-16 hours, with most users reporting about 12 hands on hours before their first print. No soldering is required for assembly, and the main required tools are all included. In addition to the included tools, things like pliers, wire cutters and similar common tools may be handy for some steps, but are not required.
Please note that consumer 3d printing is still in its infancy. The assembly of any 3d printer kit will require familiarity with basic mechanics, wiring, and computer skills. In order to help you through the process, we provide you with detailed instructions and we are available via email or web chat to help guide you if you get stuck. Should you have any concerns about your ability to complete the assembly, please reach out to us. We'll be happy to work with you to determine if the MendelMax2 is right for you.

All Maker's Tool Works products are under constant development as we receive feedback from our customers and improve the products, so the exact contents of the kit are subject to change.

  1. An Enjoyable First Week.

    Posted by Loren McConnell on 27th May 2013

    I have had about a week with the MM2, and I am pleased with my purchase and its potential. This is my first 3D printer, though I have prior experience in CNC machining, Arduino programming and other technical hobbies, so this is a natural thing for me. My friends with other 3D printers have been impressed with my first prints and I'm confident that the quality will improve as I dial-in the machine and my workflow. After a couple of evenings of calibration, I have managed to produce good quality parts, including press-fit tolerances and gearing.


    The printer assembly process went well for me, and I was printing in the first weekend after the kit arrived having put in a couple of days' effort. All parts are of good quality, and well packaged. The nuts and bolts came packaged separately in labeled bags. There are numerous "extras" in the kit to ease assembly -- a selection of metric hex wrenches, Kapton tape, thread locking compound, and wire shrouds. It's clear that care has been taken to make this a complete kit. I did need to a tube of high temp silicone adhesive to mount the extruder heat module, but that is readily available at automotive supply stores.

    Understand, though that his _is_ a kit and that assembly will take considerable time (12+hrs) and attention to detail. The instructions are carefully written, with an itemized parts lists and photographs for each step. Read carefully, and study the pictures. Stay organized and count your parts at each step. "Always be knolling." (http://en.wikipedia.org/wiki/Knoll_(verb)) You are likely experience a smooth build.

    The build process actually includes a "bootstrapping" step. After completing the basic assembly and software installation, you will print your own fan and end-stop mounts then update the firmware to use them. I really enjoyed this process, and it is a great education in how to use the machine, change firmware, and upgrade the machine -- all with parts that you will really use. I recommend going a little further -- study the firmware "Configuration.h" file (Rambo) and understand the calibration options. It is good knowledge to have, and you may want to adjust them later. Make sure to keep a backup copy of the originals.

    After my first couple of prints, I logged in to the #MakersToolWorks Freenode IRC channel to celebrate. I was surprised to get immediate responses from MTW employees (on a Sunday afternoon) and from other MM2 users. Maxbots himself offered some advice on improving PLA adhesion -- use a thin film of diluted PVA glue (Elmer's white Glue-all) on the build platform. (http://www.youtube.com/watch?v=FuQ2EabKBDo) This is excellent advice an has worked flawlessly for me so far. The company seems dedicated to supporting their users in this forum. I was immediately asked for a critique of the printer assembly process, and I'll be sending some suggestions.

    I enjoyed a successful first print using the firmware and Slic3r settings recommended in the MM2 instructions. Since then, I have spent some time doing calibration tests to improve my results. The "slicing" software DOES need fine tuning to get the best results. I recommend following the calibration processes linked below. Take care in bed leveling and Z 0-height calibration -- that really makes a difference. Be methodical, take notes and label your results. This is an iterative process -- test, measure, adjust, repeat. In my experience, the machine is consistent enough that small adjustments produce the results that they should.


    Enjoy your printer. You may follow me on Thingiverse to see how my experience evolves.
