Abstract: The stop time of a whole apparatus caused by planning of shaping, maintenance, replacement of a material, or the like is shortened. A three-dimensional laminating and shaping apparatus includes a plurality of shaping chambers, at least one material supplier that supplies a material of a three-dimensional laminated and shaped object onto a shaping table in each of the shaping chambers, at least one light beam irradiator that irradiates the material with a light beam, and a controller that controls the material supplier and the light beam irradiator. If the material supplier supplies the material onto one of the shaping tables, the controller controls the light beam irradiator to perform irradiation of the light beam onto the other one of the shaping tables.

Abstract: This invention provides a laminating and fabricating control apparatus for correcting a laser irradiation position in correspondence with a shift of the laser irradiation position during laminating and fabricating by an optical fabricating unit. The laminating and fabricating control apparatus controls a laminating and fabricating unit that includes a squeezing blade configured to spread a laminating material on an upper layer of a laminated and fabricated object, and an irradiator configured to irradiate the laminating material, to fabricate the laminated and fabricated object. The laminating and fabricating control apparatus includes a position shift acquirer that acquires a shift of an irradiation position of irradiation light on a surface of the squeezing blade when receiving the irradiation light from the irradiator, and an irradiation position corrector that corrects the irradiation position by the irradiator based on the shift of the irradiation position.

Abstract: This invention provides a three-dimensional laminating and fabricating system that can remove the influence of a gas flow between the irradiation positions by a plurality of irradiators. The three-dimensional laminating and fabricating system includes a laminating and fabricating unit that includes a plurality of irradiators configured to irradiate a laminating material, and a remover configured to generate a flow path on a laminated surface and remove dust generated by the irradiated laminating material, to cause the plurality of irradiators to perform irradiation to fabricate each layer of a laminated and fabricated object made of the laminating material as an aggregate of cell regions, and a laminating and fabricating controller that controls selection of each of the cell regions to be irradiated by each of the plurality of irradiators so as to prevent the dust generated in each of the cell regions on an upstream side of the flow path from influencing fabricating in each of the cell regions on a downstream side of the flow path.

Abstract: A system of this invention is a three-dimensional laminating and fabricating system that suppresses, in advance, a squeezing blade from getting caught on a surface of a laminated and fabricated object. The three-dimensional laminating and fabricating system includes a laminating and fabricating unit that includes a squeezing blade configured to spread a laminating material on an upper layer of a laminated and fabricated object, and an irradiator configured to irradiate the laminating material, and fabricates each layer of the laminated and fabricated object as an aggregate of cell regions, and a laminating and fabricating controller that controls the laminating and fabricating unit such that a scanning direction in which the irradiator irradiates the laminating material in the cell region changes with respect to a moving direction of the squeezing blade during laminating and fabricating.
