FDM TPU

Material details

Thermoplastic polyurethane, or TPU, is a very common form of elastic polymer or elastomer, capable of being printed on FDM 3D printers. Of the many kinds of flexible 3D printer filaments, TPU is slightly more rigid, which makes it easier to manufacture and use. FDM TPU has a Shore hardness in the range of 85A-95A and is a medium-strength material with very high flexibility and durability; it is able to withstand much higher compressive and tensile forces than its more common counterparts PLA and ABS. Note: Flexibility varies based on the infill amount.
