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).

Abstract: The present invention relates to a sinter powder (SP) comprising at least one semicrystalline terephthalate polyester (A), at least one amorphous terephthalate polyester (B) and at least one phosphinic salt (C). 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, to a shaped body obtainable by the method of the invention, and to the use of a phosphinic salt in a sinter powder (SP) for broadening the sintering window (WSP) of the sinter powder (SP).
