Document Type and Number:
WIPO Patent Application WO/2014/188778
Kind Code:
A1
Abstract:
The problem addressed by the present invention is to provide a production method for a three-dimensional shaped article, in which the properties (physical and chemical properties) of each part of one component (product) differ, and a metal powder is used as a material. One embodiment of the present invention is a production method for a three-dimensional shaped article, the method comprising the following: a mixing step for obtaining a dissimilar metal mixed powder by mixing a first metal powder (P1) and a second metal powder (P2) different from the first metal powder (P1); and a shaping step for sintering, or melting and solidifying, the dissimilar metal mixed powder obtained in the mixing step. Based on the part of the three-dimensional shaped article to be produced, the mixing ratio of the first metal powder (P1) and the second metal powder (P2) is changed in the mixing step.
