    摘要: An apparatus for making a three-dimensional object includes a table, a powdery layer-former that forms a powdery layer on the table, and an optical beam-irradiator that irradiates an optical beam on a predetermined region of the powdery layer to sinter the predetermined region of the powdery layer. A chamber for accommodating the table and the powdery layer-former and a lid for opening and closing an opening defined in the chamber at a location immediately above an optical beam-irradiating range are provided. The three-dimensional object is taken out from the chamber through the opening upon completion of the sintering, and the optical beam-irradiator is disposed at a position deviated from immediately above the optical beam-irradiating range to obliquely irradiate the optical beam on the powdery layer.

    摘要: 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.
