    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°.

  • Publication number: 20160371398
    Abstract: An apparatus according to this invention is an information processing apparatus that efficiently combines and arranges a plurality of three-dimensional fabricating models by simple processing. The information processing apparatus includes a grid generator that generates three-dimensional grids by dividing a three-dimensional virtual area by a predetermined size, a converter that converts a plurality of three-dimensional fabricating models into aggregate models of the three-dimensional grids respectively including the three-dimensional fabricating models, a moving unit that relatively moves the aggregate models without overlapping each other, and an arrangement determiner that determines, if an arrangement of the aggregate models satisfies a predetermined condition, the arrangement of the aggregate models as an arrangement of the plurality of three-dimensional fabricating models.
