| description | PROBLEM TO BE SOLVED: To provide a method for producing a molding reduced in a dimensional change after molding and also having required hardness.SOLUTION: Provided is a method for producing a molding comprising: a molding step in which a recoat step where material powder is uniformly scattered over a molding table to form a material powder layer and a molding step where laser light is applied to the prescribed place(s) of the material powder layer to form a sintered layer are repeated to form a desired molding; and a carburization treatment step where the molding is subjected to carburization treatment. The material powder is a ferrous material having a carbon content of 0.1 mass% or lower.SELECTED DRAWING: Figure 1
【課題】造形後の寸法変化が少なく、且つ必要な硬度を有する造形物の製造方法を提供する。【解決手段】本発明のいくつかの態様によれば、造形テーブル上に材料粉体を均一に撒布して材料粉体層を形成するリコート工程と、前記材料粉体層の所定箇所にレーザ光を照射して焼結層を形成する焼結工程とを繰り返して、所望の造形物を形成する造形工程と、前記造形物を浸炭処理する浸炭処理工程と、を備え、前記材料粉体は、炭素含有量が０．１質量％以下の鉄系材料である、造形物の製造方法が提供される。【選択図】 図１ |
