Diamond LINE - TPU (Flexible)

Filament Innovations

TPU (Thermoplastic Polyurethane) is a fun an exciting filament that is flexible and gives the user endless possibilities for creative and real-world uses. TPU allows a user to print an object, bend and flex the object, and then have it go back to its original printed shape. TPU offers great elongation properties as it can stretch and bend, and durability in real world applications (i.e. a smartphone case). While there are numerous TPU polymers available, we believe we have found the best one for both ease of 3D Printing and elasticity.  

Note* Our TPU polymer is not recommended for Bowden extruders. If you have clogs, please lower your print speed and retraction settings - TPU is a difficult polymer to successfully print for new users.
