Abstract: The present invention relates to a process for producing a polyamide powder (PP) comprising at least one semicrystalline polyamide (P) and at least one additive (A). The semicrystalline polyamide (P) and the at least one additive (A) are initially compounded with one another in an extruder and subsequently introduced into a solvent (SV) in which the at least one semicrystalline polyamide (P) then crystallizes to obtain the polyamide powder (PP). The present invention further relates to the thus obtainable polyamide powder (PP) and to the use of the polyamide powder (PP) as sintering powder (SP) and also to a process for producing a shaped body by selective laser sintering of a polyamide powder (PP).
