Abstract: The present invention relates to a sinter powder (SP) comprising a first polyamide component (PA1) and a second polyamide component (PA2), where the melting point of the second polyamide component (PA2) is higher than the melting point of the first polyamide component (PA1). The present invention further relates to a method of producing a shaped body by sintering the sinter powder (SP) or by an FFF (fused filament fabrication) method, and to a shaped body obtainable by the methods of the invention. The present invention further relates to a method of producing the sinter powder (SP).
