Filament Heated Dry Box

thingiverse

This is a heated Filament Dry Box that can allow filament to be printed straight from the box. The bowden tubes can be moved to the extruder at print time. The tubes have plugs at the enclosure bungs to seal them when not in use. This requires wiring 110V AC so there is a hazard risk if you are not knowledgeable about the wiring please get help. I wired a 10amp breaker between the controller and heater/fan for safety. I also used a bulkhead main plug for supply power. A bulkhead gland could be used to save cost. All holes in the box were sealed with silicon adhesive. There is a descendant stand on the lid. The photos show my implementation. I purchased small cloth bags and pore the descendant into the bag then place on the shelf. Once you complete the build it can take a few days to reach single digit humidity depending on how dry the air is to start with. Instructions for setting the temp and humidity limits can be found on YouTube for the controller. Its very simple. I set start temp at 42c and cutoff at 48c. That is safe for all filaments and good for drying the air. The humidity I set to come on at 15% and cutoff at 10%. I ran the hot line into the supply side of the humidy relay, then from the output of the humidity relay to the supply side of the temp relay and from the output side of the temp relay to the 10amp breaker. From the 10amp breaker to the heater and fan. I printed all parts with ASA and it is living comfortably at those settings. This box holds 5 spools. The spools ride on 608 bearings with a 3/4" pvc pipe running through the center to hold the spools in place when they start getting low.
