PolyFlex TPU90
PolyFlex is a family of high-quality flexible materials. It provides the perfect solution for applications where high flexibility and durability are required.
PolyFlex TPU90, created from Covestro’s Addigy family, is a thermoplastic polyurethane (TPU) based filament designed to provide great flexibility without compromising on printing speed. It also has the ability to resist ultra-violet (UV) light or sunlight.
Printing PolyFlex TPU90?
We highly recommend to use a direct drive printer to print PolyFlex™ TPU90. A direct drive printer is a printer with the extruder mounted on top of the hot end.
