To provide a three-dimensional molding machine in which reliability of each of a molding accuracy and durability of the machine is improved.
The three-dimensional molding machine comprises a powder laminating unit 120, a colored carrier imparting unit 160, an ultraviolet illuminator 170, and a binder imparting unit 150 sequentially disposed from a -X direction toward +X direction so as not to enable scanning them to a housing 180 in a sub-scanning direction (a direction along the X-axis), and a powder shielding unit S provided to prevent powder from being scattered between a layer forming unit 112 and the unit 160. When the layer 112 is formed in a molding tank 112, the tray 110 having the layer 111 is reciprocated and moved in the sub- scanning direction to the housing 180, the tray 110 forms the powder layer 112 when the tray 110 is moved in the +X direction. Meanwhile, when the tray 110 is moved in the -X direction, application of a binder irradiation with ultraviolet ray and application of a color ink are implemented to the layer 112.
