I got sick of cursing at my foaming filament so I adapted the design from a wood drying kiln and built my self a nice filament drying kiln this weekend.
I used two 100W light bulbs wired in parallel with a dimmer. Built a 3' tall x 12" wide box out of 3/4" foil covered insulation board and foil tape. Used some wire grill and flashing to get the filament out of the direct heat of the bulbs. I put a few holes in the top and bottom to let air move.
The two 100W bulbs are overkill, but the dimmer adds a lot of flexibility. I used a temp sensor on my multimeter to set the heat at 85° C.
I stack the spools, let them bake for 4-6 hours then store them in an airtight cooler filled with heavy duty desiccant.
