Although a TPU is commonly thought of as a flexible filament, this stuff is the toughest filament I have ever used. Don’t let that fool you though. It prints easy. Just up your nozzle temp to 240 and let it run. Being a TPU I recommend a glue stick on PEI beds to protect from damage. No extra nozzle wear is expected. This post isn’t so much about the color but the filament itself. It comes at a high price for half a kilogram but understand you are getting nylon performance at relatively low and easy print settings. It did string a bit for me, good side clippers are recommended.
