In this video I will show you how I cut my 3D printing times by half, and in some cases by 2/3rds by swapping in a .6mm nozzle and tweaking settings in Prusa Slicer on my Prusa MK3S 3D printer. Even if you use the default .4mm nozzle, you are going to benefit from the slicer changes that increase the infill speed and improve your bridging.
I have been using Amazon Basics PETG. Specifically, I have used a roll of the black, gray, white, and transparent. Check that out here: https://amzn.to/2QQNbbC
