Assembly Technician

Boulder, CO

We build ultra low cost metal 3D printers and run a growing fleet of plastic and metal printers. You will get hands-on time building real machines, learning practical assembly skills, and seeing how a printer goes from a pile of parts to a functioning system. To get a better sense of our mission and who we are, check out this interview of our founder.
