The present invention provides a sintered powder for selective laser sintering (SLS), a method for producing the same, a method for producing a compact, and a compact. The sintering powder for selective laser sintering comprises at least one polyamide and at least one metal soap selected from salts of fatty acids, montanic acids or dimer acids having at least 10 carbon atoms. Contains species. [Effects] The molded product made of the powder according to the present invention has improved appearance and surface characteristics, and improved reusability of the unsintered powder, as compared with conventional products. The shaped bodies produced from the re-used sintered powders have clearly improved mechanical properties, in particular the modulus of elasticity, compared to prior-art shaped bodies based on the re-used conventional polyamide 12 powder. And elongation at break. Furthermore, the moldings according to the invention have approximately the same density as the injection moldings. [Selection diagram] None |
