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 mouldings 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 moulding can be removed from the powder bed. The mouldless 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： The present invention relates to a sinter powder composed of polyamide which also comprises PMMI, PMMA, or copolymers with PMMI, in particular PMMI-PMMA copolymers, to the use of this sinter powder for laser-sintering, and also to moldings produced from this sinter powder. The moldings made from the powder of the invention have marked advantages over conventional products in their appearance and in their surface quality, especially as far as roughness and dimensional stability during selective laser sintering (SLS) are concerned. In addition, moldings produced from the sinter powder of the invention also have better mechanical properties than moldings based on conventional nylon-12 powders, in particular in terms of modulus of elasticity and tensile strength. These moldings also have a density close to that of injection moldings.

摘要： The present invention relates to a polymer powder which comprises polyamide, and to the use of this powder for shaping processes, and also to moldings produced from this polymer powder. The shaping processes are layer-by-layer processes which use powders, where regions of the respective layer are selectively melted via introduction of electromagnetic energy. The selectivity may be achieved, with no intention of restricting the invention thereto, be achieved via masks, application of inhibitors, of absorbers, or of susceptors, or via focusing of the energy introduced. After cooling, the regions then solidified can be removed in the form of moldings from the powder bed.

摘要： The present invention relates to a polymer powder composed of polyamide or of copolyamides, which also comprises flame retardant, in particular phosphonates, to a layer-by-layer process which selectively melts regions or selectively binds them, and also to moldings produced from this polymer powder. Compared with conventional products, the moldings constructed using the powder of the invention exhibit marked advantages in flammability and combustibility and drop behavior, particularly with respect to UL® (Underwriters Laboratories) classification. Furthermore, moldings produced from polymer powder of the invention have adequately good mechanical properties when compared with moldings based on polymer powders without flame retardant, in particular in terms of modulus of elasticity and tensile strain at break. In addition, these moldings also have a density close to that of injection moldings.
