Abstract

BASFSE INV/WOW PF0000077314 SE/WOW 33 EB14-7314PC “as originally filed” Kaolin for mechanical reinforcement of polymeric laser sinter powder The present invention relates to a process for producing a shaped body by selective 5 laser sintering of a sinter powder (SP). The sinter powder (SP) comprises at least one polyamide (P) and in the range from 10% to 50% by weight of at least one aluminosilicate. The at least one aluminosilicate has a D50 in the range from 2.5 to 4.5 µm. The present invention further relates to shaped bodies obtainable by the process of the invention. 10
