POWDER MATERIAL USED FOR POWDER LAMINATION MOLDING AND POWDER LAMINATION MOLDING METHOD USING THE SAME
PROBLEM TO BE SOLVED: To provide a powder material used for a powder lamination molding method, which has excellent fluidity.SOLUTION: A powder material of the present invention is a powder material used for a powder lamination molding method and is constituted from particles having a form of secondary particles in which primary particles are three-dimensionally bonded with a gap. The secondary particles are granulated sintered particles obtained by granulating the primary particles into spheres and by sintering the same. Alternatively, the powder material is constituted from at least one kind of material selected from the group consisting of a metallic material, a ceramic material and a cermet.SELECTED DRAWING: Figure 2
【課題】流動性のよい粉末積層造形に用いる粉末材料を提供する。【解決手段】本発明の粉末材料は、粉末積層造形に用いる粉末材料であって、当該粉末材料が、一次粒子が間隙をもって三次元的に結合されてなる二次粒子の形態を有している粒子から構成されている。二次粒子は、前記一次粒子を球形に造粒し、焼結してなる造粒焼結粒子である。あるいは、粉末材料は、金属材料、セラミック材料およびサーメットからなる群から選択される少なくとも一種の材料により構成されている。【選択図】図２
