A Rubber-like flexible material.
TPU boasts extreme flexibility and even remains flexible in colder environments. This flexibility also means it can retain its form after taking impacts.
Printing with this material can cause issues; Due to it’s ability to flex, the filament can have trouble feeding into the extruder and causing jams and clogs. A direct drive feeding system is recommended to prevent this. It is possible to print TPU with a Bowden set up, although the results are less consistent than using a direct drive.
Used in: Vibration dampening applications, RC Car Tyres, Phone Cases, Rubber Ducks.
