The is provided a stacked-layers forming device comprising a powder layer-forming part 2 for forming a powder layer Sa, an optical device for forming a solidified layer Sb by irradiating a predetermined portion of the powder layer Sa with a light beam and a powder replenishing means 5 for supplying the powder material M to above a base 40 on which the powder layer Sa and the solidified layer Sb are stacked or onto an upper surface of a base frame 41 which surrounds the base 40. The powder replenishing means 5 comprises an approximately cylindrical member 50 in which the powder material M is charged and a screw member 51 which is installed within the approximately cylindrical member 50 wherein a rotation of the screw member 51 conveys the powder material M in the approximately cylindrical member 50. The stacked-layers forming device 1 of the present invention enables it to not only curb its height since the powder material M can be conveyed in a screw manner, but also achieve an improved cycle of the material
