Oooh, now that's something I'd never thought to do before.
cold smoke my filament !
Hot diggity that might actually be a thing lol
Wonder how it would effect prints. Might have to throw a roll in the smoker next time I cold smoke something.

As far as my filament being effected by moisture.
Hasn't happened yet. even on wet days my workshop is pretty stable: between 48-54% RH
Most filament rolls come with large sealable bags with a silicon pouch inside. But much of my filament is just stacked in the raw.
Pla is apparently relatively unaffected by it anyway.
Likewise I've not had any issues with pet-g not stored in bags either.

Stuff like nylon is always kept in bags with desiccant.

And #40fan - get yourself an excalibur dehydrator. Temperature controlled. Also great for making snackstix. :-)
