摘要： PROBLEM TO BE SOLVED: To provide a laminate molding device for molding a three-dimensionally shaped article, wherein a large-sized shaped article can be molded with a small covering frame, and the using amount of an atmospheric gas is reduced.
SOLUTION: The laminate molding device 1 is provided with: a base 22; a material holding frame 34 surrounding the base 22 and holding a powder layer 32; a powder layer forming part 3 for forming the powder layer 32; a covering frame 36 of which the upper face is provided with a window 36a permeating a light beam L and also the lower face is opened, and which moves on the horizontal plane of the material holding frame 34 so as to cover the powder layer 32; and a light beam irradiation part 4 for irradiating the powder layer 32 with light beam L so as to form a solidified layer 33. The projection area of the covering frame 36 is smaller than the area of a processing area E on which a shaped article 11 is molded. Since the covering frame 11 moves while covering the powder layer 32, even if the covering frame 36 is small, the area of the processing area E is made widen so as to mold a large-sized shaped article 11, and since the projection area of the covering frame 36 is small, the using amount of an atmospheric gas can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a production device of a metal powder sintered component, wherein the irradiation area of a light beam is widen, and the scanning precision of the light beam is improved.
SOLUTION: The production device 1 of the metal powder sintered component comprises a powder layer forming section 2 for forming a powder layer 12 by supplying metal powder 11, a light beam irradiating section 3 for irradiating a predetermined part of the powder layer 12 with a light beam to sinter the powder layer 12 thus forming a sintered layer 13, and a cutting section 3 for cutting a molding 14 which is laminating the sintered layers 13 integrally. The light beam irradiating section 3 has a scanning head X-axis 37x for moving a scanning head 37 in the X direction in parallel with the light beam irradiation plane, and a scanning head Y-axis 37y for moving a scanning head 37 in the Y direction wherein the scanning head 37 moves in the direction parallel with the irradiation plane, and emits the light beam. Since the scanning head moves in parallel with the irradiation plane, the irradiation area can be widened, thus a large metal powder sintered component can be produced, and since the irradiation height may be low, scanning precision of the light beam is good.

SOLUTION: A metal optical molding processing machine (1) comprises a powder layer forming section (2), an irradiating section (3) for irradiation with a light beam (L), a correction target (4) to which a correction mark becoming the reference for correcting the light beam irradiating position is put, and an imaging camera (5) for imaging the position of the correction mark. The correction target (4) is made of such a material as dissolving through irradiation with the light beam (L) and a through-hole is made. The correction target (4) is mounted on a molding plate (23) and irradiated with the light beam (L), thus putting a correction mark (7) while penetrating the correction target (4). Thereafter, the correction mark (7) is imaged by means of the camera (5) and the position of the correction mark (7) is measured in order to correct the irradiating position. Since the correction mark (7) is formed while penetrating, contrast becomes clear, the position of the correction mark (7) is measured easily, and the irradiating position with the light beam (L) can be corrected easily.
