Building a 3d-printer filament dryer and storage box.
I mostly print nylons and PC and with the humidity here in HI it's a big pain to keep it dry enough. Even drying the spools in the oven doesn't really work because it takes days for the inner parts to dry out. So instead I'm building a heated and dehumidified box that will hold 8 spools and can feed the filament directly into the printer. The box itself is foam and fiberglass, the heater I'm reusing an old 3d printer bed heater, and the dehumidifier a thermoelectric element from a broken wine refrigerator.

- joshvm 7y agoThe solution that Markforged uses for this is a modified Peli Case with a hole for the bowden tube. Seems to work pretty well.
- lutorm 7y agoYeah I've seen what people have made but they mostly appear to be modestly heated enclosures with desiccants. Desiccants get saturated very quickly here unless the box is super sealed (that's what I've been using for storage so far) so it's a drag. I also want to be able to heat this to maybe 80-85C to really dry out the nylon continuously in situ, so it has to be pretty well insulated or you'll use a ton of energy.
- joshvm 7y agoInteresting, we have the "cheap" Markforged printer - $15k hah - which seems to be stupidly reliable (never had a failed print). Their drybox isn't heated at all by the way, so it's not clear how much it makes a difference, but then we're not in a particularly humid area (North England) and the lab has air con.
