Abstract
There is provided a stacked-layers forming device including a powder layer-forming part for forming a powder layer, an optical device for forming a solidified layer by irradiating a predetermined portion of the powder layer with a light beam and a powder replenishing means for supplying the powder material to above a base on which the powder layer and the solidified layer are stacked or onto an upper surface of a base frame which surrounds the base. The powder replenishing means includes an approximately cylindrical member in which the powder material is charged and a screw member which is installed within the approximately cylindrical member wherein a rotation of the screw member conveys the powder material in the approximately cylindrical member. The stacked-layers forming device of the present invention enables it to not only curb its height since the powder material can be conveyed in a screw manner, but also achieve an improved cycle of the material since the powder material can be conveyed in one direction.
