Instructables member, Gosse Adema has used Lego building blocks combined with Nema 17 stepper motors to create his very own and very awesome Lego 3D printer.
The 3D printer was crewed using a number of resources from the web to build the components together with a heated bed and controller board. Watch the video below to see it in action.
“This LEGO printer is based on the Prusa I3 rework printer. The printer started as a A4-plotter with stepper motors from an old HP printer. After upgrading the stepper motors to Nema 17 motors I decided to build a X, Y and Z axis machine. This evolved in this printer.
LEGO and Nema 17 stepper motors are a perfect match. A default LEGO brick of 4 by 2 studs is 32 x 16 x 9.6 mm. Nema stepper motors have m3 holes at a distance of 31 mm. Attaching the Nema 17 stepper with LEGO technic, using a felt damper/isolator and m3 x 15 bolts, gives a solid base (image 4). See this Lego Dimension Guide for more lego math.
This is my first instrucable and it will not be a guide for creating this exact printer. I will give enough details to create such a printer. All information used to build this printer comes from the internet.”
