Still Up and Coming: Non-Planar FDM 3D Printing With 3 or 6 Axes

Most of the time FDM 3D printing involves laying down layers of thermoplastics, but the layer lines also form the biggest weakness with parts produced this way. Being able to lay out the lines to follow the part’s contours can theoretically strengthen the part and save material in the process. Recently, [Michael Wüthrich] demonstrated an approach that uses a modified Prusa Mini FDM printer to first lay out a part in PETG using non-planar printing, after which this PETG part was used to print on top of in PLA, effectively using the PETG as a ‘printbed’ from which the PLA can be easily removed and leaving the PLA part as fully non-planar on both sides.
