Well for some of the bigger parts I have been trying to print, I have tried using Polylactic Acid.
The first part I printed with the PLA, belt-split-jig-universal-20ff.stl, was a great success. But the second copy wasn’t so good. I have no idea why, but perhaps the ambient air temperature of the room was different.
The second copy is on the right in the first image, and on the top in the second image. You can see that a corner lifted quite substantially during the print.
