Document Type and Number:
Japanese Patent JP7430603
Kind Code:
B2
Abstract:
To obtain a method for manufacturing a three-dimensional molding which is three-dimensionally molded by using metal powder containing impurities, and to obtain the three-dimensional molding.SOLUTION: A method for manufacturing a three-dimensional molding includes a molding step (STEP1) for molding a three-dimensional molding using metal powder containing an impurity (1), and a chemical polishing step (STEP2) for chemically polishing the inner wall of the three-dimensional molding. The three-dimensional molding is a tubular three-dimensional molding composed of a metal containing the impurity 1 and having a rectangular cross section at one end. The surface roughness of the inner wall of the tubular part of the three-dimensional molding is within a preset numerical value range.SELECTED DRAWING: Figure 1
