Abstract: The present invention relates to a sinter powder (SP) comprising at least one semicrystalline terephthalate polyester (A) which is prepared by reacting at least one aromatic dicarboxylic acid (a) and at least two aliphatic diols (b1) and (b2), where the aliphatic diol (b1) is neopentyl glycol. The present invention further relates to a method of producing the sinter powder (SP), and to a method of producing a shaped body by sintering the sinter powder (SP). The present invention further relates to the shaped body obtainable by the sintering. The present invention also relates to the use of the sinter powder (SP) in a sintering method.
