摘要

Producing three-dimensional molded body by layered construction, comprises forming several layers in superimposed planes by printing method, and subjecting the obtained three-dimensional green body to heat treatment for expelling the organic components and for sintering to obtain the final molded body. The formation of each layer is carried out using a polymer that is not soluble in a first solvent, a second solvent for the polymer, which is miscible or soluble with the first solvent, and a powder which is formed from metallic-, ceramic- and/or glass particles. Producing three-dimensional molded body by layered construction, comprises (a) forming several layers in superimposed planes by printing method, and (b) subjecting the obtained three-dimensional green body to heat treatment for expelling the organic components and for sintering to obtain the final molded body. Each layer is formed as a two-dimensional structure specific for the layer. The formation of each layer is carried out using a polymer that is not soluble in a first solvent, a second solvent for the polymer, which is miscible or soluble with the first solvent, and a powder which is formed from metallic-, ceramic- and/or glass particles.
