PROBLEM TO BE SOLVED: To provide a powder material feeder for a three-dimensional molding apparatus which manufactures three-dimensional molded products from powder material, capable of suppressing the occurrence of irregularities in a powder material layer and molding an accurately molded product at a higher speed than before.SOLUTION: A powder material feeder 7 includes: an outlet 22 from which a powder material 2 is discharged onto a molding table 5; a flattening member 24 located back of the outlet 22 in the moving direction of the powder material feeder 7 when the powder material feeder 7 supplies the powder material 2 onto the molding table 5, which flattens a powder material layer 4 discharged onto the molding table 5 from the outlet 22 to a predetermined thickness by levelling for removal of an excess amount of powder material 31; and a suction device 40 having a suction nozzle 41 for suctioning the excess amount of powder material 31 produced in the levelling by the flattening member 24. 【課題】粉体材料によって三次元造形物を製造する三次元造形装置の粉体材料供給装置において、粉体材料の層の凹凸の発生を抑止して、精度の高い造形物を従来よりも高速で造形することができるものを得る。【解決手段】粉体材料供給装置７を、造形テーブル５に粉体材料２を排出する排出口２２と、前記粉体材料供給装置７が該造形テーブル５に粉体材料２を供給する際の該粉体材料供給装置７の移動方向において前記排出口２２よりも後ろ側に位置して、該排出口２２から前記造形テーブル５に排出された粉体材料の層４を、余剰な粉体材料３１を摺り切りながら予め定められた厚さに平坦化する平坦化部材２４と、該平坦化部材２４により擦り切られた余剰な粉体材料３１を吸引する吸引ノズル４１を有する吸引装置４０とを備えた構成とする。【選択図】図２
