I’ve seen many debates about the need to dry PLA filaments. Looks like some people never need to do anything while others dry the hell out of them before printing.

I’ve been recommended once to print at 10% RH… After 48h of drying, I can barely get below 37%…

So: what’s the humidity level in the room your printer is?

    I live in a dry climate. I don’t bother with PLA, but I dry PETG. I printed some stuff from a roll of PETG that had been open longer than a year, and looking closely at the melted plastic coming out of the nozzle, there was noticeable bubbles and stringing during printing. Once dried, all went away. People who claim you don’t need to dry some filaments must not care much about quality.
