Abstract: The present invention relates to a process for producing a three-dimensional component by means of selective laser sintering (SLS), wherein a processing temperature Tx is established in a build chamber, and a powder layer consisting of a thermoplastic polymer powder is provided in the build chamber. The thermoplastic polymer powder comprises a blend of a semicrystalline polymer, an amorphous polymer and a polymeric compatibilizer. The polymer powder is then melted in a spatially resolved manner by means of a directed beam of electromagnetic radiation, wherein binding of the regions of the melted and resolidified polymer layer by layer in multiple steps affords a three-dimensional component. In the process of the invention, the temperature in the build chamber during the performance of the individual steps varies by not more than +/−10% from the processing temperature Tx set. In addition, the processing temperature Tx differs by not more than +/−20 K from the processing temperature Tx(A) of a polymer powder comprising the corresponding semicrystalline polymer as the sole polymeric component.
