A new material that makes 3D prints more flexible without compromising on durability has been developed. The material is called Flexible Plastic, a thermoplastic polyurethane (TPU) that's notable for its ability to produce soft 3D prints that remain functional, developed by Sculpteo. Sculpteo says Flexible Plastic rates a Shore hardness level of 65A, which is below what you typically see in the 3D printing market. In practical terms, that means items printed with Flexible Plastic will have some give to them.
