METHOD FOR PRODUCING THREE-DIMENSIONAL MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a three-dimensional molding with metal powders in which the properties (physical-chemical properties) of the respective parts in one component (product) are different as the stock.SOLUTION: Provided is a method for producing a three-dimensional molding comprising: a mixing step of mixing the first metal powder P1 with the second metal powder P2 different from the first metal powder P1 to obtain a dissimilar metal mixed powder; and a molding step of sintering or melting-solidifying the dissimilar metal mixed powder obtained in the mixing step. The mixing ratio between the first metal powder P1 and the second metal powder P2 in the mixing step is changed based on the part of the three-dimensional molding to be produced.
