  • Patent number: 11052609
    Abstract: A molding system to manufacture a three-dimensional object corresponding to a three-dimensional model. The molding apparatus includes a slice data generation unit to generate slice data from three-dimensional shape data of the three-dimensional model, and a lamination unit to laminate a layer of a molding material on the basis of the slice data. The slice data generation unit analyzes data, and, if a region in which a layer of a second molding material different from a first molding material is to be laminated on a layer of the first molding material and in which it is difficult to laminate the layers is extracted, modifies the data of a region of at least one of an ith layer and an (i+1)th layer to data in which a portion in which the first molding material is disposed and a portion in which the second molding material is disposed.

  • Publication number: 20210192262
    Abstract: In the present disclosure, a candidate area is determined based on a pixel having a specific color included in an input image, and an area is determined to be a processing target from the candidate area based on a pixel having a predetermined color different from the specific color included in the candidate area. Further, a second binary image in which a pixel corresponding to the pixel having the specific color is converted into a white pixel is generated by converting, in a first binary image obtained by the input image being binarized, a pixel that is included in the area determined to be the processing target and corresponds to the pixel having the specific color, into a white pixel.
