Budget Dehydrator Gives your Damp Filament a Second Chance

If you’ve had the misfortune of leaving your 3D printer filament out on a muggy day or, heaven forbid: showering with it, it’s probably soaked up quite a bit of moisture. Moisture will do more than just make your printer sound like Rice Crispies, it’ll ruin surface finishes and cause the filament to string into thin wisps between separate geometries on the same layer. Luckily for us, though, both [SafetyGlassesRequired] and [Joe Mike Terranella] give us the breakdown on taking a pair of snippers and about $40 in cash to start drying out our filament far away from the possibility of ruining any nearby kitchen ovens.

If you’ve been circling the 3D printer community for a while, you might have already heard about this trick. But with the arrival of a curiously-culinary-looking contraption called PrintDry, we can’t let the elephant in the room keep silent for much longer. Rather than risk our own pennies and leave ourselves stranded with a device that only makes the jerky on the box cover, [SafetlyGlassesRequired] and [Joe Mike Terranella] kindly prove our suspicions for us once and for all: a food dehydrator works perfectly for drying all that filament that we left out in the rain!

Clumsiness aside, a dehydrator isn’t a bad investment in the long run. Not only can we keep our supply dry, we might just be able to give all that freebie filament (that we dug out of the trash) a second life by resetting it to a clean, dry state.

These dehyrdators will toast all that moisture out of your filament, but it wont keep them dry whilst printing. For that problem, you’ll need to summon a heated drybox like this one.

[Joe Mike’s] solution will run us about $40. If you can do better, let us know in the comments.
