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.
