摘要： A three-dimensional object of a desired shape is made by irradiating an optical beam on a metal powder layer to form a sintered layer and by laminating such sintered layer one above another. A metal powder composition for use in making such a three-dimensional object includes an iron-based powder material, a nickel and/or nickel alloy powder material, a copper and/or copper alloy powder material, and a graphite powder material. The graphite powder material acts to enhance the wettability during melting and to reduce microcracks during solidification.

摘要： An apparatus for making a three-dimensional object includes a powdery layer-forming unit for forming a powdery layer on a table and an optical beam-irradiating unit for irradiating an optical beam on a predetermined region of the powdery layer to sinter the predetermined region. The optical beam-irradiating unit is disposed at a position spaced from immediately above an optical beam-irradiating range to obliquely irradiate the optical beam on the powdery layer. Because fumes generated by irradiating and heating the powdery layer with the optical beam rise towards a position immediately above them, the optical beam is irradiated from the position spaced from immediately above the optical beam-irradiating range, thereby reducing a cloud of the optical beam-irradiating unit that may be caused by the fumes.

摘要： A three-dimensional object is made by repeating a process. An optical beam is irradiated on a predetermined portion of a powdery layer to form a sintered layer. A new powdery layer is formed on a surface of the sintered layer. An optical beam is irradiated on a predetermined portion of the new powdery layer to form a new sintered layer united with the underlying sintered layer. Because a portion of the sintered layer that is higher than a predetermined level is removed as occasion demands, the abnormally sintered portion on the sintered layer can be removed, making it possible to prevent stoppage of the shaping process, which may be caused by the abnormally sintered portion.

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.
