POWDER MATERIAL FOR POWDER LAMINATE MOLDING AND METHOD FOR MANUFACTURING MOLDED ARTICLE
To provide a powder material for powder laminate molding with which gas is less likely to be generated even by preheating before molding, and a molded articles is manufacturable under reduced pressure by a powder laminate molding method.SOLUTION: A powder material for powder laminate molding is a powder material for manufacturing a molded article by a powder laminate molding method, and includes a secondary particle in which a plurality of primary particles are bonded to one another. A mass decrement when heat treatment is carried out under conditions of 1100°C for 2.5 hours is 0.02 mass% or less.SELECTED DRAWING: None
【課題】造形前に予熱を行ってもガスが生成しにくく減圧下で粉末積層造形法によって造形物を製造することが可能な粉末積層造形用粉末材料を提供する。【解決手段】粉末積層造形用粉末材料は、粉末積層造形法によって造形物を製造するための粉末材料であって、複数の一次粒子が結合してなる二次粒子を含有し、１１００℃、２．５時間との条件で熱処理した場合の質量減少率が０．０２質量％以下である。【選択図】なし
