Okay, I have the .20 QUALITY and the .15 QUALITY test prints done. I decided to skip the .30 DRAFT as I can tell from the preview in Prusa Slicer that it’s too rough and lacks detail. I may do a test print of that just for fun this weekend. These are the preset Print Settings that are part of the PrusaSlicer, using my Prusa i3Mk3S, in Matterhackers PLA Jet Grey PLA.
I honestly can’t really tell the difference between the .15 QUALITY and the .20 QUALITY prints–though my wife successfully did. I had to label them on the bottom to keep them straight. The difference between the print times was about an hour more for the .15 test print–and if I slice the entire model the .20 QUALITY preset is a 19h43m print, and the .15 QUALITY preset is 25h28m print–a difference of about 5 hours, 15 mins.
