Method for creating metal shaped object using metal powder by laser irradiation, forming material therefor, and created structure

摘要

PROBLEM TO BE SOLVED: To provide a creating method of a metal molded object using metal powder and a laser, which is a simple method using a low-output laser through a single process at a low energy cost per one molded object.SOLUTION: The present invention discloses: a laser sintering method, in which a formation material comprising a mixture powder of a high melting point metal powder and a low melting point metal powder is used, and the low melting point metal is fused by laser irradiation to form a structure having a metal alloy pattern; a formation material to be used for the laser sintering method; and a structure formed by the laser sintering method for forming a structure having a metal alloy pattern.EFFECT: A creating method of a metal molded object using metal powder and a laser can be provided, which is simple with a low energy cost per one molded object.SELECTED DRAWING: None
