Ohio IT professional Rick Pollack founded MakerGear, LLC in 2009 to “develop products and services for the rapidly expanding maker community with a focus on advancing digital fabrication.” Working with wife Karen, Rick has already brought two fully-developed desktop 3D printers to market—a well-regarded Prusa Mendel kit and their premium design, the Mosaic—as well as a line of accessories and upgrades for each.

I recently got my hands on a Mosaic kit, and as of this writing, I’m about halfway done with it. So far, I’m impressed with how easily it’s all going together. I’ll be documenting the build, in stages, over the next few weeks, and introduce the series with Part I: The Frame. If you’re considering a Mosaic, I hope the series will help you understand how it goes together, and, if you’ve already bought one, I hope it will be a useful reference during assembly.

  1. Sean, are you in Austin (tagged in the post)? I’m up in Round Rock and have one of the first Mosaics too. Not that you need any help, clearly, but if you do, feel free to hit me up :) 

    1. Yes I am!  Thank you for the offer, Richard.  I may well take you up on it.  You (and others) should feel free to e-mail me directly at

  2. I have one of these bad boys on order.  Always had a soft spot for Makergear since I replaced half the equpment on my Makerbot years ago with Makergear Branded stuff. :)

  3. I bought a MakerGear Prusa kit and within 5 days of receiving it I had it built, calibrated, and printing perfect parts! This is because of the high level of attention to detail that the folks at MakerGear have when they put together their kits. I also owe my success to the fantastic support that Rick from MakerGear gives, as well as from the faithful icr dwellers in #makergearv2 on freenode. Everything about this company is top notch!
