    摘要： A task often encountered in very recent times is the rapid provision of prototypes. Particularly suitable processes are those based on pulverulent materials and in which the desired structures are produced layer-by-layer through selective melting and solidification. The invention provides the constitution, production and use of a copolyamide powder which was produced using the following monomer units: a) laurolactam or ω-aminoundecanoic acid, and also b) dodecanedioic acid, and either c) decanediamine or dodecanediamine, in shaping processes, and also to moldings produced through a layer-by-layer process which selectively melts regions of a powder layer, using this specific powder. Once the regions previously melted layer-by-layer have been cooled and solidified, the molding can be removed from the powder bed. The moldless layer-by-layer processes for the production of components using the copolyamide powder result in simplified and more reliable conduct of the process and better recyclability.

    摘要翻译： 最近经常遇到的任务是快速提供原型。 特别合适的方法是基于粉末材料的方法，其中通过选择性熔融和凝固逐层地制备所需的结构。 本发明提供了使用以下单体单元制备的共聚酰胺粉末的构成，生产和使用：a）月桂内酰胺或ω-氨基十一烷酸，以及b）十二烷二酸，和c）癸二胺或十二烷二胺在成型过程中， 并且还涉及通过使用该特定粉末选择性地熔化粉末层的区域的逐层方法制备的成型体。 一旦先前已经逐层熔化的区域已被冷却和固化，则可以从粉末床中除去模制物。 用于使用共聚酰胺粉末制备组分的无霉变的逐层方法导致方法的简化和更可靠的进行和更好的可再循环性。
