I am not accustomed to taking the time to write reviews on products that I have purchased but I must make an exception with MTW’s MendelMax 3 Upgrade kit. I purchased the MendelMax 2 kit last year and was blown away by the amateur “buildability” (if there is such a word). 16 hours after receiving my shipment, I was printing. Your documentation left no questions unanswered and I was able to complete the build with absolutely no problems.

The print quality was well beyond what I expected being new to 3D printing and turned out great models from the beginning. Several months after buying this printer, I found out that the MendelMax 3 was being released. I was a bit skeptical of any claimed improvements since I really couldn’t see much room for improvements. Once I looked at the photos of the beefed up construction, I realized that the new design’s implementation of rubber rollers on the sides of the aluminum extrusions would create an infinite more precise result. Then I began looking at the real differences and was able to see a few blemishes that I was getting with the MendelMax 2 that I was certain were caused by the way the “X” and “Y” axes were traveling on their respective rails. When I found that MTW was offering an Upgrade kit, it was a no brainer for me so I placed my order.



Wow! How right I was. This kit took me a little longer to build but rightfully so since it has several more parts and is a more complex structure. This printer improved on every aspect of the MendelMax 2 that could possibly be improved upon. There were several areas that I had not even identified as deficient that the MendelMax 3 blows out of the water. This new design is not only tremendously more sturdy and precise, with the inclusion of the LED lighting and base enclosure, they were able to clean up the looks of the printer so as to hide all of the wirings and electronics allowing a true newbie like myself to create a printer that has a truly finished and clean look. I never get tired of showing it off (ask the guys at my office, they are tired of hearing me talk about it so much).

The print quality surpasses even what the MendelMax 2 was able to produce by a long-shot. I have put the equivalent of 2 spools of PLA through this new printer in the last several weeks and have not had the first print failure. I have been able to kick off a print job as I go to bed only to wake up to perfect results.

I can’t do a review of a MTW 3d printer without commenting on the guys who frequent MTW’s Web IRC chatroom acting as ongoing support for not only the products that MTW creates but any other 3d printing difficulties anyone may have. They seem to truly enjoy spending their evenings helping people with the 3D printer builds and creations. I really can’t say enough about how truly helpful these guys have been.

Thanks for a truly superior product and all of your efforts in making it a success in my home. I hope you are ready for the demand that will surely follow the release of this awesome piece of equipment.
