Flexfill TPU filament is available in two grades, which differ in mechanical properties, 98A being stiffer in its filament form, making it easier to 3D print, but with still some flexibility.

Flexfill from Fillamentum is a flexible TPU (thermoplastic polyurethane) filament that was developed with great processability and mechanical properties as main goals.

Flexfill is oil resistant with unique mechanical properties and excellent inter-layer adhesion.
