Print your 3D model in sapphire with the NinjaTek Armadillo 1.75mm 75D TPU Nylon Alternative Filament.
With a shore hardness of 75D, this thermoplastic polyurethane (TPU) nylon alternative filament has 84% better abrasion resistance than PLA and 60% better abrasion resistance than ABS. It is also resistant to many chemicals, such as naphtha, ASTM oils #1-3, petroleum, and freon. It can be used for bridging without having to worry about warping. Unlike ABS, this filament does not require a heated print bed.
