Summary

The Mulbot is an open source Mostly Printed 3D printer that features a 3Dprinted frame, bearing blocks, and drive systems. The original goal for thisproject is to further push the Rep Rap concept and to 3D print more thanjust the frame. As a result there are no purchased bearing assembles ordrive systems on this printer.

This printer utilizes square rail type 3D printed housings for linearbearings. Since the bearings and rails are printed they have beenintegrated into the frame members. 4.5mm G100 Stainless Steel bearingsballs are used to recirculate through the bearing housings to reduce fictionand to provide preload to remove bushing slop.

All three of the printers drive systems are 3D printed as well. The Y-axis isdriven by a 3D printed herringbone gear rack and pinion. The combinationof 3D printed drive and idle pulleys and a TPU belt drive the X-axis hot endcarriage. While the Z-axis utilizes 3D printed trapezoidal lead screws andnuts to translate the hotend vertically.
