Abstract: The present invention relates to a process for producing a shaped body by selective laser sintering of a sinter powder (SP). The sinter powder (SP) comprises at least one semicrystalline polyamide, at least one nylon-6I/6T and at least one polyaryl ether. The present invention further relates to a shaped body obtainable by the process of the invention and to the use of a polyaryl ether in a sinter powder (SP) for broadening the sintering window (WSP) of the sinter powder (SP).

Abstract: The present invention relates to a method for producing a molded body by the selective laser sintering of a sinter powder (SP). The sinter powder (SP) contains at least one polyamide (P) and 5 to 50 wt %, preferably 10 to 50 wt %, of at least one aluminum silicate. The at least one aluminum silicate has a D50 value in the range of 2.5 to 4.5 μm. The present invention also relates to molded bodies obtainable by means of the method according to the invention.
