  • Patent number: 6460958
    Abstract: Ejection nozzles (152a-152g) are located in a nozzle surface (153) of an ejection head (150). A distance (H: Ha-Hg) between each of the ejection nozzles (152a-152g) and a printing object (109) is obtained and compared with a permissible distance (H0) which is determined by the required level of print quality. The ejection nozzles (152a-152d) whose distances (H) from the printing object (109) are not more than the permissible distance (H0) are enabled for ink ejection, while the ejection nozzles (152e-152g) whose distances (H) are greater than the permissible distance (H0) are disabled for ink ejection. The surface of a printing object (228) is divided into a plurality of target areas (205), each of which is then approximated by a projective plane (206). Then, image data about a projected image (208) which is obtained by orthogonal projection of a print image (207) onto the projective planes (206), is obtained from print image data about an image to be printed on the surface of the printing object (228).

  • Patent number: 6360656
    Abstract: A three-dimensional object printing apparatus according to the present invention comprises: a shape recognition section for obtaining three-dimensional shape data about a surface shape of a three-dimensional object by measurement or the like; an ejection section for ejecting ink toward the three-dimensional object; a scanning section for causing the ejection section to scan relative to the three-dimensional object; and a control section for controlling an operation of the ejection section and/or the scanning section in accordance with information about inclination of the surface of the three-dimensional object, the information being indicated in the data obtained by the shape recognition section. The printing apparatus performs printing in accordance with the information obtained by measurement on the surface inclination of the object to achieve a high-quality printing process.

  • Publication number: 20020029094
    Abstract: A data generating apparatus (1) adds feel information to shape data for an object to be molded in an STL data generating section (1a). Then, a data processing apparatus (10) generates molding data for reproducing shape and feel of the object to be molded, and the molding data is supplied to a three-dimensional molding apparatus (20). The three-dimensional molding apparatus (20) performs molding on the basis of the molding data obtained from the data processing apparatus (10). The resulting three-dimensional molded matter faithfully reproduce not only the shape but also the feel of the object to be molded. In this way, the present invention was made to generate a three-dimensional molded matter which faithfully reproduces feel of the object.
