Desiccant packet dehumidifier?

3 years ago by Anonymouse to c/3dprinting

Has anybody used one of these mini "dehumidifiers" to dry out filament as a substitute for buying a bunch of the desiccant beads? My filament seems OK, but I could do better to keep it dry.

I've used these in a drybox to keep filament dry, and they work really well for that, but to actually dry filament I use what amounts to a modified food dehydrator. You really need heat and airflow to get moisture out of already wet filament. If you don't have a food dehydrator you can use, you can also try an oven, but be careful of temperature fluctuations which could cause it to get too hot and melt your filament.

I've used up my filament fast enough to not have to dry it, but if you're storing it in a decently sealed box with this thing or desiccant, what happens that the filament would need to be dried in a dehydrator?

Desiccants aren’t magic, they can’t get 100% of the water out of the air, however they prolong the life of the filament SUBSTANTIALLY.
