Dankdryer

Some engineering filaments specify drying at temperatures up to 140C. Standard filament dryers can't approach this temperature (most peak at 70--80C). How to construct one that can handle it?

We need materials and electronics which can operate in such an environment. Ideally, we'll keep most of the electronics out of the heated chamber, but it'll likely be quite warm immediately outside as well. This seems possible for everything but our sensors, which must necessarily be within the chamber. We'll need a thermostat, and might want a humidity sensor. We'll also have a load cell to weigh the spool/chamber, and thus let us know how much water has been evaporated. I haven't been able to find a humidity sensor rated above 100C, so that's a nonstarter. We'll want to put the thermostat on lengths of wire.

We might want to drive the ceramic heating element via AC, as it will presumably want significant wattage, necessitating an expensive AC adapter.
