This invention provides a three-dimensional laminating and fabricating system that can remove the influence of a gas flow between the irradiation positions by a plurality of irradiators. The three-dimensional laminating and fabricating system includes a laminating and fabricating unit that includes a plurality of irradiators configured to irradiate a laminating material, and a remover configured to generate a flow path on a laminated surface and remove dust generated by the irradiated laminating material, to cause the plurality of irradiators to perform irradiation to fabricate each layer of a laminated and fabricated object made of the laminating material as an aggregate of cell regions, and a laminating and fabricating controller that controls selection of each of the cell regions to be irradiated by each of the plurality of irradiators so as to prevent the dust generated in each of the cell regions on an upstream side of the flow path from influencing fabricating in each of the cell regions on a downstream side of the flow path.

This invention provides a three-dimensional laminating and fabricating system that shortens the scanning time of a divided scanning region and shortens the fabricating time of three-dimensional laminating and fabricating. The three-dimensional laminating and fabricating system includes a laminating and fabricating unit that includes at least one irradiator configured to irradiate a laminating material and fabricates each layer of a laminated and fabricated object made of the laminating material as an aggregate of cell regions, and a laminating and fabricating controller that controls the laminating and fabricating unit such that the irradiator irradiates the laminating material in each of the cell regions by performing spiral scanning along sides of a scanning region that is used to irradiate the cell regions by the irradiator and has a shape including at least five vertices with an interior angle of not less than 90&#xb0;.
