Recently I have been making TPU “rubber” 1.75 filament myself since the different extruder companies I contacted could not reach the tolerances required. I have found a good technique and are now building a dedicated extruder that I can easily duplicate so that I can get a “extruder farm” up and running. All that takes time and for the fun of it I did a test print today, as you can see the result is amazingly good :)
