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).
