TPU flexi

TPU is durable thermoplastic material with excellent qualities which, as one of the few, offers the possibility of printing flexible and elastic components. Undoubtly its advantage is the high impact resistance or excellent wear resistance.TPU (thermoplastic polyurethane) is available in two basic hardnesses Shore 98A and 92A. A unique feature among 3D printed materials is up to 600% elongation to tear.

Typical use

the ideal choice for 3D printing of prototypes and functional parts that require flexibility, abrasion resistance and high chemical resistance.

Design guide

Maximum size1: 250 x 210 x 200 mm
Minimal wall thickness: 0,8 mm
Minimum detail size2: 0,4 mm
Layer height: 0,1 – 0,3 mm

1 largest model size printed as one piece, larger models are required to be printed as separate parts but they can easily be connected
2 details and structures of models smaller than the minimum details size can be wrongly portrayed or get lost entirely



The final model can be edited further to achieve smooth surface. All kinds of modeling or acrylic sealant sprays are effective in sealing.


FDM (Fused deposition modeling) technology prints models by layering thin layers of material made from melted plastic fibers. This creates a firm structure with laminated surface.
