Abstract
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°.
