Abstract (en)
[origin: WO2017140764A1] 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.
