This article is about the Mulbot Printer.
PLEASE NOTE: This is the current home for community generated documentation (Please Contribute!).
The Mulbot is an open source Mostly Printed 3D printer that features a 3D printed frame, bearing blocks, and drive systems. The original goal for this project is to further push the Rep Rap concept and to 3D print more than just the frame. As a result there are no purchased bearing assembles or drive systems on this printer.
This printer utilizes square rail type 3D printed housings for linear bearings. Since the bearings and rails are printed they have been integrated into the frame members. 4.5mm G100 Stainless Steel bearings balls are used to recirculate through the bearing housings to reduce fiction and to provide preload to remove bushing slop.
All three of the printers drive systems are 3D printed as well. The Y-axis is driven by a 3D printed herringbone gear rack and pinion. The combination of 3D printed drive and idle pulleys and a TPU belt drive the X-axis hot end carriage. While the Z-axis utilizes 3D printed trapezoidal lead screws and nuts to translate the hotend vertically.
