Material comparison
Flexible, elastic and shock absorbing; for rubber-like parts. Support-free flexible parts and lattices; insoles, gaskets, protection. So which one is right for your project? Compare the values, strengths and weaknesses side by side.
Most popularThermoplastic polyurethane
TPU 95A is a medium-hard flexible material with a hardness of 95 Shore A. It is used in parts that need flexibility and shock absorption, for both prototypes and end products of rubber-like items.
Thermoplastic polyurethane and elastomer powders
TPU printed in a powder bed allows far more complex flexible geometries than FDM TPU. Midsoles, protective pads and shock-absorbing lattice structures are typical applications.

Decision
Good to know
TPU 95A has higher tensile strength: 35 MPa, versus 9 MPa for TPU / TPE (SLS / MJF).
TPU 95A stretches further before breaking: 800 %, versus 280 % for TPU / TPE (SLS / MJF).
TPU / TPE (SLS / MJF) is usually easier to produce; it needs less special equipment and tuning.
In general, TPU 95A is more economical. The exact price is set in the quotation based on part size, quantity and technology.
