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.

摘要： A method of manufacturing a three-dimensionally shaped object by irradiating a metallic material with light beams, wherein the metallic material is supplied at a high density to increase the density and the strength of the three-dimensionally shaped object. The method of manufacturing a three-dimensionally shaped object comprises: an irradiation step of irradiating a metal mesh (2) formed of metal wires and a powder layer (3) formed of metal powder with light beams (L) to form a solidified layer or molten layer; and a laminating step of repeatedly performing the irradiation step for metal meshes to form a three-dimensionally shaped object. In the method, both of the metal mesh (2) and the metal powder are supplied in combination as the metallic material. Therefore, the method enables to supply the metallic material at a higher density compared to the case where metal powder is supplied alone, and enables to produce a three-dimensionally shaped object with higher dimensional accuracy, higher density and higher strength.

摘要： An object of the present invention is to easily eliminate fumes inside a chamber, so as to improve a positional accuracy of irradiation with a light beam and a machining accuracy in a method for manufacturing a three-dimensional shaped object. A stacked-layers forming device 1 includes a powder layer forming unit 3, a light beam irradiating unit 4, a base 22 which is fixed and on which a powder layer 32 is formed, a lifting/lowering frame 34 which surrounds the circumference of the base 22 and is freely capable of being lifted and lowered, a cover frame 36 which has a window 36a allowing transmission of light beam in its top surface, and whose bottom surface is opened, and which is disposed on the lifting/lowering frame 34 to form a chamber C, and a gas tank 71 for supplying an ambient gas. The lifting/lowering frame 34 is lowered to reduce the volume of the chamber C, so as to discharge fumes generated inside the cover frame 36, which performs replacement with the ambient gas. Since the volume of the chamber C is reduced, it is possible to easily eliminate the fumes, which makes it possible to improve the positional accuracy of irradiation with the light beam L, and the machining accuracy.

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.
