    摘要： A process of debinding a ceramic product utilizes a furnace for heating the ceramic product therein in the presence of a surrounding gas so as to remove an organic binder contained in the ceramic product. The ceramic product is continuously heated to an elevated temperature during which the organic binder is decomposed to generate a cracked gas. The process monitors the condition of the cracked gas and controls, depending upon the monitored condition, to vary a temperature gradient at which the ceramic product is heated and at the same time to vary an amount of the surrounding gas being supplied to the furnace in such a manner as to remove the organic binder successfully from within the ceramic product without leaving any unacceptable defect therein.

    摘要： A process of debinding a powder compact formed from a mixture of a sinterable powder and an organic binder utilizes a furnace for heating therein the powder compact at a pressure lower than an atmospheric pressure in order to remove an excess amount of the organic binder. A control is made to vary the furnace pressure and/or a heating rate in accordance with a monitored parameter so as to effectively and successfully removed an excess amount of the organic binder which would cause an unacceptable defect in a finished product. The parameter is selected as indicative of a condition of the furnace or a cracked gas being generated by decomposition of the organic binder, and includes, for example, a furnace temperature, density, volume, or the other measurable characteristics of the cracked gas.

    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 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： A metal powder for use in a metal laser-sintering wherein a three-dimensional shaped object is produced by irradiating a powder layer of the metal powder with a light beam to form a sintered layer and thereby laminating the sintered layers. The metal powder of the present invention is characterized in that it comprises an iron-based powder and at least one kind of powder selected from the group consisting of a nickel powder, a nickel-based alloy powder, a copper powder, a copper-based alloy powder and a graphite powder; and the iron-based powder has been annealed. In such metal powder, the iron-based powder is in a softened state due to the annealing treatment thereof. Accordingly, the use of the metal powder in a metal laser-sintering process makes it possible to reduce a machining resistance attributable to the residual metal powder adherent to the surface of the shaped object, which leads to an achievement of an extended lifetime of a machining tool.

    摘要： Disclosed is a mold for resin injection molding that can realize rapid heating or cooling. A resin injection molding mold includes a cavity mold and a core mold and is produced on a base plate by metal photofabrication. The cavity mold is provided with a cavity warm water circuit for allowing warm water for heating to flow and a cavity cold water circuit for allowing cold water for cooling to flow. The core mold is also provided with a core warm water circuit and a core cold water circuit. The core mold includes an air blowing passage for feeding warm air or cold air into a resin molding part and a suction passage (36) for sucking a gas within the resin molding part. The resin molding part side of the air blowing passage and the suction passage is formed of a low-density shaping part that has a low metallic powder sintered density and is permeable to gas. Warm air or cold air can be blown through the low-density shaping part, whereby rapid heating or cooling of the resin injection molding mold can be realized.

    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.
