Based on the 1st generation of Artifex 3D Printer, the Artifex 2 comes with a redesigned extrusion mechanism to handle both flexible materials (e.g., NinjaFlex) and standard rigid materials (e.g., PLA, ABS) in one extruder without tool change. The Artifex 2 also offers other new features, including dual extrusion capability (Artifex 2 Duo version), LCD controller for untethered printing and on-board control, and other enhancements. Both fully assembled and DIY kit packages are available at http://www.3dmakerworld.com/store/3dprinters. Slic3r and Cura configuration files are provided for various settings at http://www.3dmakerworld.com/support/downloads. Some printing videos: See the attached Build Instructions and User Manual.
