Super simple prototype but if it works... Very cool idea!

I doubt this will work with faster printing materials. 40mm/s is suuuuper slow compared to speeds that most modern printers are spitting filament with (not necessarily TPU). Unless you have a coil or something inside the tube heater so it spends longer time in there, but that probably also introduces a lot of resistance so moving the material through is notably harder.

Wonder if you could use some sort of buffer system to extend the time in the dryer

What about a pre-extruder or a set (or pultruder?) that brings it to just below the glass transition temp, but still at the original filament size? Water boils off, plastic is left!
