This snow white SemiFlex 3D filament (1.75mm) is a flexible TPU filament type, which is slightly stiffer than Ninjaflex. Semi Flex can print objects in any shape, provides elastic end results and has a shore hardness of 98A. TPU filament is characterised by high elasticity and excellent wear resistance. However, the print speed is limited and not every extruder is suitable for this material. So first check whether your 3D printer is suitable.
