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.

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.
