| description | A method for producing a shaped body, containing: producing the shaped body from a composition by a powder-based layer construction process, wherein the composition contains a thermoplastic polyurethane, obtained by reacting a polyisocyanate composition and a polyol composition, the thermoplastic polyurethane is solid at least in a temperature region below 50° C. and has end groups selected from the group consisting of first end groups and second end groups, wherein the first end groups are optionally eliminated at a first temperature, and the second end groups are optionally eliminated at a second temperature, to form reactive groups on the thermoplastic polyurethane that optionally enter into a reaction with functional groups of the thermoplastic polyurethane or functional groups of a further component of the composition, and wherein the first temperature and the second temperature are each greater than or equal to 60° C. |
