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： Manufacturing equipment for a metal powder sintered component includes: a powder layer forming portion that supplies metal powder to form a powder layer; a light beam irradiator that irradiates a give point on the powder layer with light beams to sinter the powder layer and thus form a sintered layer; and a cutter that cuts a shaped object in which sintered layers are integrally stacked. The light beam irradiator has a scan head X shaft that moves a scan head in X direction parallel to a surface irradiated with light beams and a scan head Y shaft that moves the scan head in Y direction, so that the scan head moves in a direction parallel to the irradiated surface to perform irradiation with light beams. Since the scan head moves parallel to the irradiated surface, the irradiated area can be increased. Since the irradiation height can be small, the accuracy of light beam scanning can be enhanced.

摘要： To make a three-dimensional object, an optical beam is first irradiated on a predetermined portion of a powder layer to form a sintered layer, which is then covered with a new powder layer. The optical beam is again irradiated on a predetermined portion of the new powder layer to form another sintered layer that has been united with the underlying sintered layer. These processes are repeatedly carried out to form a plurality of sintered layers united together, which have a size greater than that of a target shape of the three-dimensional object. A surface region of a shaped object formed by then is removed during the formation of the plurality of sintered layers.
