Abstract

See full text

It is a feature of a use of an elastic polymer for production of a porous body (in an additive manufacturing method that the porous body comprises a three-dimensional network of node points joined to one another by struts, and a void volume present between the struts, where the struts have an average length of ≧200 μm to ≦50 mm and the struts (100) have an average thickness of ≧100 μm to ≦5 mm. The polymer here is an elastomer selected from the following group: thermoset polyurethane elastomers (PUR), thermoplastic copolyamides (TPA), thermoplastic copolyesters (TPC), thermoplastic olefin-based elastomers (TPO), styrene block copolymers (TPS), thermoplastic urethane-based elastomers (TPU), crosslinked thermoplastic olefin-based elastomers (TPV), thermoplastic polyvinyl chloride-based elastomers (PVC), thermoplastic silicone-based elastomers and a combination of at least two of these elastomers.
