THREE-DIMENSIONAL PRINTING APPARATUS, METHOD FOR THREE-DIMENSIONAL PRINTING, AND COMPUTER-READABLE STORAGE MEDIUM

摘要

When first cross-sectional image data representing a target model corresponding to a shape of a three-dimensional printing object, and second cross-sectional image data representing both of the target model and a support model corresponding to a shape of a member assisting the creation of the three-dimensional printing object, are recognized to match each other by at least a predetermined ratio, the second cross-sectional image data is stored on storage means as third cross-sectional image data. By contrast, when the first cross-sectional image data and the second cross-sectional image data are recognized not to match each other by at least the predetermined ratio, synthesis data of the first cross-sectional image data and the second cross-sectional image data is stored on the storage medium as the third cross-sectional image data. The three-dimensional printing object is created based on the third cross-sectional image data.

1. A three-dimensional printing apparatus that creates a three-dimensional printing object based on three-dimensional data representing a shape of the three-dimensional printing object; the three-dimensional printing apparatus comprising:
first cross-sectional image data creation means that creates first cross-sectional image data representing a target model corresponding to the shape of the three-dimensional printing object, from a plurality of cross-sectional shapes continuous in a predetermined direction, by use of the three-dimensional data; second cross-sectional image data creation means that creates second cross-sectional image data representing both of the target model and a support model corresponding to a shape of a member assisting the creation of the three-dimensional printing object, from a plurality of cross-sectional shapes continuous in the predetermined direction, by use of the three-dimensional data; determination means that compares the first cross-sectional image data and the second cross-sectional image data against each other to determine whether or not the first cross-sectional image data and the second cross-sectional image data are recognized to match each other by at least a predetermined ratio; synthesis means that synthesizes the first cross-sectional image data and the second cross-sectional image data to create synthesis data; and storage means that stores the second cross-sectional image data or the synthesis data as third cross-sectional image data; wherein: when the determination means determines that the first cross-sectional image data and the second cross-sectional image data are recognized to match each other by at least the predetermined ratio, the second cross-sectional image data is stored on the storage means as the third cross-sectional image data; when the determination means determines that the first cross-sectional image data and the second cross-sectional image data are recognized not to match each other by at least the predetermined ratio, the synthesis data is stored on the storage means as the third cross-sectional image data; and the three-dimensional printing object is created based on the third cross-sectional image data.
