This is the most interesting thing I’ve done with my 3D printer in some time. Instead of printing in a series of 2D planes stacked up to form a 3D shape (2.5D), this non planar technique creates geometry with true 3D tool paths that can eliminate the steps often seen on shallow surfaces. Based on the amazing Masters Thesis of Daniel Ahlers and the University of Hamburg, this development can be tried yourself if you are willing to put in some time to setting it up.

In this video I’ll lead you through step by step on how to setup a virtual Linux machine on your PC, compile the custom version of Slic3r and then share with you my results. The future is bright and I thank people like Daniel Ahlers  and Moritz Walter for leading the way.
