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. ## Claims ### Claim 1 A three-dimensional laminating and shaping apparatus comprising: a plurality of shaping chambers having shaping tables, respectively; a plurality of material suppliers that supply materials of three-dimensional laminated and shaped objects onto said shaping tables in said plurality of shaping chambers, respectively; a plurality of light beam irradiators that emit light beams that irradiate the materials on said shaping tables; and a controller that includes a moving unit that moves all of said plurality of light beam irradiators between said plurality of shaping chambers and controls said plurality of material suppliers and said plurality of light beam irradiators, wherein at a timing when shaping of a first of the three-dimensional laminated and shaped objects is completed on a first of said shaping tables in a first of said plurality of shaping chambers using a first of said plurality of material suppliers, said controller (1) stops use of the first of said plurality of shaping chambers during a first stopped period so that a user can, during the stopped period, extract the completed first three-dimensional laminated and shaped object, and plan for shaping a third three-dimensional laminated and shaped object in said first of said plurality of shaping chamber, (2) moves said plurality of light beam irradiators onto a second of said plurality of shaping tables in a second of said plurality of shaping chambers, and (3) starts shaping of a second of the three-dimensional laminated and shaped objects in said second of said plurality of shaping chambers using a second of said plurality of material suppliers, and at a timing when shaping of the second of the three-dimensional laminated and shaped objects is completed on the second of said shaping tables in the second of said plurality of shaping chambers using the second of said plurality of material suppliers, said controller (4) stops use of the second of said plurality of shaping chambers during a second stopped period so that the user can, during another stopped period, extract the completed second three-dimensional laminated and shaped object and plan for shaping a fourth three-dimensional laminated and shaped object in the second of said plurality of shaping chambers, (5) moves said plurality of light beam irradiators onto the first of said plurality of shaping tables in the first of said plurality of shaping chambers, and (6) starts shaping of the third three-dimensional laminated and shaped object in the first of said plurality of shaping chambers using the first of said plurality of material suppliers. ### Claim 2 (depends on 1) The three-dimensional laminating and shaping apparatus according to claim 1, further comprising galvanometer mirrors, and drivers that drive said galvanometer mirrors to guide the light beam onto each of the shaping tables. ### Claim 3 (depends on 1) The three-dimensional laminating and shaping apparatus according to claim 1, wherein said moving unit comprises one of a slide rail and a linear rail. ### Claim 4 (depends on 1) The three-dimensional laminating and shaping apparatus according to claim 1, wherein said controller further includes a shaping schedule generator that generates and stores a shaping schedule of shaping the three-dimensional laminated and shaped objects in said plurality of shaping chambers, and controls said material suppliers and said plurality of light beam irradiators based on the shaping schedule. ### Claim 5 (depends on 1) The three-dimensional laminating and shaping apparatus according to claim 1, wherein the plan for shaping the third three-dimensional laminated and shaped object in said first of said plurality of shaping chambers includes planning for refilling a material storage for the first of said plurality of shaping chambers with a material, cleaning an interior of the first of the plurality of shaping chambers, and performing maintenance on the first of the plurality of shaping chambers, and the plan for shaping the fourth three-dimensional laminated and shaped object in the second of said plurality of shaping chambers includes planning for refilling a material storage for the second of said plurality of shaping chambers with the material, cleaning an interior of the second of the plurality of shaping chambers, and performing maintenance on the second of the plurality of shaping chambers. ### Claim 6 (depends on 1) A control method of a three-dimensional laminating and shaping apparatus comprising the steps of: (a) providing the three-dimensional laminating and shaping apparatus according to claim 1, (b) causing the first material supplier to supply a first material onto the first shaping table in the first shaping chamber, and causing the plurality of light beam irradiators to irradiate a second material in the second shaping chamber with the light beams; (c) causing the second material supplier to supply a second material onto the second shaping table in the second shaping chamber, and causing the plurality of light beam irradiators to irradiate the first material in the first shaping chamber with the light beam; and (d) repeating the steps (b) and (c) while moving the plurality of light beam irradiators between the first and second shaping chambers. ### Claim 7 (depends on 1) A non-transitory computer readable medium storing a control program for the three-dimensional laminating and shaping apparatus according to claim 1, wherein the program is configured for causing a computer to execute a method comprising the steps of: (a) causing the first material supplier to supply a first material onto the first shaping table in the first shaping chamber, and causing the plurality of light beam irradiators to irradiate a second material in the second shaping chamber with the light beams; (b) causing the second material supplier to supply a second material onto the second shaping table in the second shaping chamber, and causing the plurality of light beam irradiators to irradiate the first material in the first shaping chamber with the light beams; and (c) repeating the steps (a) and (b) while moving the plurality of light beam irradiators between the first and second shaping chambers.
