You can’t tell filament moisture just by looking, though. It takes a hygrometer to know how the filament is doing moisture-wise. Just put the spool in a gallon ziplock bag with a hygrometer and seal it. After 30-45 minutes the value should stop changing and that lets you know how wet your filament is. For PLA I don’t print it if it’s above 25%. It prints best for me below 20% RH in that test. Others with different printers and environments may be higher or lower in what works for them.
Oh I see…I always assumed it needed to be heated before you can trust the humidity level. Wild…I had no idea it was always steaming to a point. At a certain point, does it dry itself by sitting?
