Print your 3D model in steel with the NinjaTek NinjaFlex 3mm 85A TPU Flexible Filament.
With a shore hardness of 85A, this thermoplastic polyurethane (TPU) flexible filament has 68% better abrasion resistance than PLA and 20% better abrasion resistance than ABS. Designed to be flexible, this filament features up to 660% elongation, which allows for repeated movement and impact without wear or cracking. The composition can also help reduce vibration. This filament doesn’t need glue or tape when printing on a standard print bed. It is also resistant to many chemicals, such as naphtha, ASTM oils #1-3, petroleum, and freon.

The material is ridiculously flexible, like soft spaghetti. I can do things few other filaments can. The material is very hygroscopic (Moisture Absorption) and in little time (2-3 hours of open exposure) shows evidence of hissing, popping at nozzle and surface anomalies on the print. The Ninjatek website does not really describe this well. First time users or inexperienced users do your homework on TPU filaments before jumping into this material. If you have the capability to print (nozzle and hot end) with your machine, regenerate/dehydrate and store this material, its awesome stuff. Made Covid-19 respirator masks that are conformal to facial contours. I will buy more. The sapphire color is absolutely stunning.
