TPU Filament

FYI: TPU filament is extremely hygroscopic. I left it on my printer for 3 days and then put it in my dryer, it registered at 65% humidity. I had to dry it 3 times to get it to 38%.

I knew something was going on as I tried to print a couple things and it popped and crackled the whole time.

That is good info right there. I have never tried that filament and now that I know, will definitely have a dryer on hand just for it.

Also to note. My ender cr6 se has a bowden tube system that I changed to capricorn tubing. The TPU filament does well going through it. I always thought you had to have a direct feed extruder to use it.
