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 polyamide MXD6 (A), at least one semicrystalline polyamide (B), optionally at least one additive (C) and optionally at least one reinforcer (D). The present invention further relates to a method of producing a shaped body using the inventive sinter powder (SP), to a shaped body obtained by this method and to the use of the inventive sinter powder (SP) in a sintering method. In addition, the present invention relates to a method of producing the sinter powder (SP) and to the use of at least one semicrystalline polyamide (B) in a sinter powder (SP) comprising at least one polyamide MXD6 (A) for improving the mechanical properties of shaped bodies made from said sinter powder (SP).

Abstract: The present invention relates to a method of producing a shaped body, wherein, in step i), a layer of an amorphous sinter powder (SP) comprising at least 70% by weight of at least one amorphous polyamide selected from the group consisting of polyamide 6I/6T and polyamide DT/DI is provided, and, in step ii), the layer provided in step i) is selectively sintered. The present invention further relates to a method of producing an amorphous sinter powder (SP) and to an amorphous sinter powder (SP) obtainable by that method. The present invention also relates to use of the amorphous sinter powder (SP) in a sintering method, and to shaped bodies obtainable by the method of the invention.
