So tried out some PETG for the first time, and the first couple prints went really well. but I believe it’s picked up quite a bit of moisture, sitting in the basement.
What’s the current recommendation for a filament dryer? there was one on /r/3dprintingdeals a bit back, a Sunlu S2. is the S1 good enough, or should someone who’s fairly recreational with everything spring for a S2? I see food dehydrators recommended sometimes, is there anything specific to look for in one?
The number of photos I’ve seen of completely melted filament rolls, due to either poor oven thermostats or inattentive users … I cannot endorse this technique.
If you’re on a budget, probably better to just power up your heated bed, with a box over top, and dry your spool inside there.
Repurposed food dehydrators seem to rate highly, if you can find a used one for cheap.
I ended up biting the $40 bullet and grabbing a Filadryer S2 when it was on sale.
That, and if your filament has anything toxic that can off-gas when you heat it, you probably don’t want it in your oven (if you use your oven for cooking food).
I’m not sure which filaments are or are not going to have any additives that might be problematic, but since almost nobody actually says what’s in their filaments, it’s probably a good idea to just assume it’s all not good for you and keep it away from your oven.
