Creating Prior Art: Filament changers equipped with dynamic filament drying

 I have a Prusa MMU filament changer on my 3D printer and I just watched this video about dynamic real-time filament drying.  Why are we drying filament this way? (youtube.com).

I wanted to go on the record creating prior art for an automatic filament changer or loading system that includes a forced-air heater that loads and dries the filament in real-time as it's printing.
