Three-dimensional laminating and shaping apparatus, control method of three-dimensional laminating and shaping apparatus, and control program of three-dimensional laminating and shaping apparatus

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.
