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.
