Abstract: The present invention relates to a thermoplastic polymer powder and to the use thereof as material for selective laser sintering (SLS). The polymer powder contains a partially crystalline polymer, an amorphous polymer and a compatibilizing agent, and optionally additional additives and/or auxiliary substances, wherein the partially crystalline polymer, the amorphous polymer and the compatibilizing agent are in the form of a polymer blend. The invention also relates to a method for producing the thermoplastic polymer powder and to a method of selective laser sintering (SLS).
