Abstract: The present invention relates to a method for producing a moulded body by selective laser sintering of a sintered powder (SP). The sintered powder (SP) contains at least one partially crystalline polyamide, at least one polyamide 6I/6T and at least one reinforcing agent. The invention also relates to a moulded body obtained according to the claimed method and to the use of polyamide 6I/6T in a sintered powder (SP), which contains at least one partially crystalline polyamide, at least one polyamide 6I/6T and at least one reinforcing agent, for broadening the sintering window (WSp) of the sintered powder (SP).
