Abstract: A method is provided, in which three-dimensional objects are manufactured by layer-wise solidifying powdery synthetic material by impact of electromagnetic or particle radiation, wherein the powdery synthetic material has an anti-microbial property so that the manufactured objects comprise surfaces having an anti-microbial effect. The anti-microbial property is achieved by additives which are present in each powder grain. Such additives can be noble metals, for example argent. The manufactured objects are mainly used in particular in the food industry and in medical engineering.

Abstract: A method for reducing the crystallization temperature and the melting temperature of a polyamide powder resulting from the polymerization of at least one predominant monomer, in which the reduction in the crystallization temperature is greater than the reduction in the melting temperature, the method including a step of polymerization of the at least one predominant monomer with at least one different minor comonomer polymerized according to the same polymerization process as the at least one predominant monomer, the at least one minor comonomer being chosen from aminocarboxylic acids, diamine/diacid pairs, lactams and/or lactones, and the at least one minor comonomer representing from 0.1% to 20% by weight of the total blend of the monomers(s) and comonomer(s), preferably from 0.5% to 15% by weight of the total blend, preferably from 1% to 10% by weight of the total blend.
