Most people know that a microwave works by exciting water molecules, but I’m not interested in the dangers of the high voltage/current of a magnetron. I wonder what might be possible with scrap consumer drivers such as a piezo, speaker drivers, or ultrasonic inducers, preferably at a frequency outside of the core human audible spectrum.
- Would an induced vibration in an around 60°C, lightly convective environment, likely significantly increase the evaporation rate of water moisture absorbed within the filament of a spool of consumer grade 3d printing filament such as PLA, PETG, PC, TPU, or Aramid?
- Would certain frequencies likely alter performance?

Just curious but is this for a side/thought experiment?
Reason I ask is cause:
why not use silica desiccants? These are fairly cheap, easy to obtain, and quite widely known in the 3D printing space.Silica is great for preventing it from getting humidified (is that the right word for this?), but if you’re trying to get the moisture out of already humidified filament it won’t really help.
