The 3DMakerWorld Artifex is an open source desktop 3D printer. The printer's frame is based on the frame of MendelMax-2.0, and the design was heavily modified for printability, strength, wire management, vibration reduction, filament feeding, and compatibility with other features in the extruder and heated build platform. As an open source 3D printer, the 3DMakerWorld Artifex was designed with the inspiration from many others' work in the open source 3D printing community.
