Abstract: In three-dimensional laminating and shaping, a three-dimensional laminated and shaped object having a corner portion is accurately shaped. A three-dimensional laminating and shaping apparatus includes a material supplier that supplies a material of a three-dimensional laminated and shaped object onto a shaping table, a light beam irradiator that performs irradiation of a light beam, a controller that controls a scanning direction and scanning speed of the light beam, a shaping model acquirer that acquires a shaping model of the three-dimensional laminated and shaped object, a shaping route decider that decides shaping routes based on the acquired shaping model, an extractor that extracts, from the decided shaping routes, a start point and end point of the shaping routes and a relay point at which a direction of the shaping route changes, and an additional route decider that decides additional routes for at least one of the extracted start point, end point, and relay point. The controller controls the scanning direction and scanning speed of the light beam based on the shaping routes and the additional routes.

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.
