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.
