    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： In order for a surface of a three-dimensional sintered object to be smoothly finished by removing unwanted portions and an excessively sintered growth formed during sintering to form sintered layers, the three-dimensional sintered object is formed by repeating successive processes of dispensing a powdery material and directing an optical sintering beam to the powdery material to form the sintered layer, until a required number of integral laminated bodies are formed. During the formation of the integral laminated bodies, trimming is applied to a first zone different from a second zone in which each laminated body is formed, to remove unwanted portions of the respective laminated body.

    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.
