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.
Aren't silica beads $5 or so a pound? How much do you use?
There are probably cheaper bulk options--but I personally bought some 50g satchets that change color when they start to saturate, for convenience. 3 of those keep a large bin dry for a few months depending on ambient humidity and how often you open it.
Yeah, you can easily order okay to decent quality silica beads for $6-15 a pound(~400g). Same colored stuff that is in the satchets, that you can dry in a dehydrator, the oven or even microwave.
You might be good with what you have, but thought I'd mention it in case you were going to restock or others wanting a bunch to stay safe.
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.
Thats true, and a good point.
But as long as you go straight from the original packaging to your dry box, you shouldn't have to worry much about it ever getting wet to begin with.
