David tells us how he designed his rPrint 3D printer. A university project he has been working on for the last 9 months.
Everything is custom, including the world’s lightest weight direct drive extruder head, Sarrus linkage build plate, linear rail guides, and his awesome bubble enclosure.
Not to mention his own custom controller, gcode interpreter, and highly optimised C++ string libraries.
