surface finish on TPU

TPU is a flexible thermoplastic elastomer used frequently in the world of additive manufacturing. It being a flexible filament makes it all the trickier to print with, with issues in build plate adhesion, layer adhesion, surface finish and extrusion.

This video looks at a few 3d printed parts in TPU and makes some points on the surface finish and overall build quality of these parts. Somethings mentioned include: dual extrusions, support material, direct drive & constrained extrusion systems, build plate adhesion, layer shifting, rough surface finish and more... all in 1 minute and 36 seconds (or as youtube says 1 min and 37 seconds... ugh).
