Left: I opened a sealed roll of a filament purchased in 2018 and I printed that rose
Right: I dried that filament in the creality dryer overnight and sent the print again
This pic was taken on 10th April. After drying the filament I put it back in storage and I forgot about it until it exploded today
It’s crazy easy too. You can get a decent size plasric tote with weatherproof gasket for about $15-20, and a few packs of reusable dessicant packs will.run another $10-15.
For about $30 all in you can keep 6-8 rolls of filament below 10%RH full time with zero hassle.
That’s a good way to keep filament dry, but it takes a very long time to remove moisture from filament that way. It’s a lot faster to use a dryer/dehydrator before putting it in the dry box.
