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： In a method for producing a three-dimensionally shaped object, a powder layer is formed by feeding a powdery material to a substrate and a solidified layer is formed by irradiating a light beam on a specified portion of the powder layer to sinter or melt the specified portion of the powder layer. A three-dimensionally shaped object having a plurality of solidified layers laminated one above another is obtained by repeating the powder layer formation and the solidified -layer formation. In the method, a stress is preliminarily applied to the substrate to reduce the amount of deformation of the substrate after production of the shaped object prior to the powder layer forming step.

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.
