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： 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： An equipment for metal-laser sintering process includes a powder layer forming unit, an irradiation unit which irradiates light beams, a correction target on which a correction mark serving as a fiducial in correction of the irradiation points of the light beams is formed, and an imaging camera which takes an image of the correction mark. The correction target is formed of a material which is melted by irradiation of light beam so as to be formed a through hole. The correction target is disposed on the substrate and the light beams are irradiated to penetrate the correction target so that the correction mark is formed. Subsequently, the imaging camera takes an image of the correction mark and the location of the correction mark is measured, and thus, correction of the irradiation points is performed. Since the correction mark is formed to be a through hole, contrast becomes clear so that location of the correction mark can be measured easily, and the correction of the irradiation points of the light beams can be performed easily.
