  • Publication number: 20170266883
    Abstract: An information processing apparatus is configured to provide data for manufacturing an object to an additive manufacturing apparatus that manufactures the object by layering a material based on a cross-sectional shape of the object. The information processing apparatus includes a memory storing a program and a processor configured to execute the program to implement processes of detecting a shape change coordinate at which a shape of the object changes based on data relating to the shape of the object, determining a height at which the cross-sectional shape of the object is to be generated such that the height includes the shape change coordinate, and generating the cross-sectional shape of the object at the determined height.

  • Publication number: 20170165918
    Abstract: An information processing apparatus used for an additive manufacturing system includes a circuitry configured to calculate a contact area of a contact face of a three dimensional (3D) model that contacts a base member of an additive manufacturing apparatus, calculate an adhesive force that is to occur to the contact face of the 3D model and the base member, rotate the 3D model by changing an angle of the 3D model with respect to a 3D modeling area, calculate a warping force that is to occur to the 3D model when the 3D model is to be formed into a 3D object under each orientation set for the 3D model by rotating the 3D model by changing the angle of the 3D model with respect to the 3D modeling area, and search for a target orientation of the 3D model where the warping force becomes smaller than the adhesive force.

  • Publication number: 20170124223
    Abstract: A modeling processing system is provided. The modeling processing system includes an acquisition unit, a memory, and a searching unit. The acquisition unit acquires information on a surface profile of a target three-dimensional object from a reading unit. The target three-dimensional object is a target for a modeling processing. The memory stores, for a plurality of modeled objects, a plurality of modeled object information, and each modeled object information includes surface profile information and internal structure information of the modeled object. The searching unit specifies, from among the plurality of modeled object information stored in the memory, at least one of the plurality of modeled object information based on the information on the surface profile of the target three-dimensional object acquired by the acquisition unit, as a candidate modeled object information for the modeling processing.
