We all know materials like Nylon and TPU typically print better after a run through a filament dryer, but when it comes to PLA and PETG, things get a little less certain. Some swear by a pre-print bake for flawless results, while others think it’s a waste of electricity. I think the truth is somewhere in the middle. Drying diehards (dryhards?) are probably doing it more than they need to, while those who think it's an overblown 3D printing trope are missing out on the benefits.

Where do you draw the line?
