METHOD FOR MANUFACTURING MOLDED ARTICLE
To provide a method for manufacturing a molded article, by which a dense molded article in a three-dimensional shape with high hardness can be manufactured.SOLUTION: The method for manufacturing a molded article includes: a step of forming a molded article in a three-dimensional shape by use of a powder material for additive manufacturing, the powder material comprising tungsten carbide and cobalt, by irradiation with laser light or an electron beam; a step of heat-treating the molded article in a reduced pressure environment; and a step of subjecting the heat-treated molded article to a hot isotropic pressing process.SELECTED DRAWING: Figure 3
【課題】緻密で硬度が高い３次元形状の造形物を造形することが可能な造形物の製造方法を提供する。【解決手段】造形物の製造方法は、タングステン炭化物及びコバルトを含む積層造形用の粉末材料を用いて、レーザ光又は電子ビームを照射して３次元形状の造形物を形成する工程と、造形物に減圧雰囲気中で熱処理を施す工程と、熱処理が施された造形物に熱間等方圧加圧加工を施す工程と、を含む。【選択図】図３
