SOLID OBJECT SHAPING APPARATUS, CONTROL METHOD FOR SOLID OBJECT SHAPING APPARATUS, AND CONTROL PROGRAM FOR SOLID OBJECT SHAPING APPARATUS

摘要

A solid object shaping apparatus includes a head unit, and a curing unit, in which a model indicating a shape and a color of a solid object to be shaped is approximated with a set of voxels each having a predetermined rectangular parallelepiped shape, a unit shaping body formed by a single dot or a plurality of dots is formed in the voxel, and the solid object is shaped by using the plurality of unit shaping bodies, and in which the plurality of unit shaping bodies constituting the solid object include a first and second unit shaping body. In the second unit shaping body, two or more faces forming a surface of the second unit shaping body correspond to a surface of the solid object, and a proportion of an inner portion of the model occupying the second unit shaping body is equal to or less than a reference value.

主权项

1. A solid object shaping apparatus comprising:
a head unit that ejects a liquid containing a colorant component; and a curing unit that cures the liquid ejected from the head unit so as to form a dot, wherein a model indicating a shape and a color of a solid object to be shaped is approximated with a set of voxels each having a predetermined rectangular parallelepiped shape, a unit shaping body formed by a single dot or a plurality of dots is formed in the voxel, and the solid object is shaped by using the plurality of unit shaping bodies, wherein the plurality of unit shaping bodies constituting the solid object include a first unit shaping body having an amount of colorant components required to represent the color indicated by the model; and a second unit shaping body having an amount of the colorant components which is smaller than the amount required to represent the color indicated by the model, and wherein, in the second unit shaping body, two or more faces of six faces forming a surface of the second unit shaping body correspond to a surface of the solid object, and a proportion of an inner portion of the model of the second unit shaping body to the entire second unit shaping body is equal to or less than a first reference value.
