Abstract

Provided is a three-dimensional object formation apparatus including: a discharging unit which discharges a plurality achromatic colored liquids and a colorless transparent liquid; and a curing unit which cures a liquid discharged from the discharging unit to a formation table to form a plurality of voxels configuring a three-dimensional object on the formation table, in which a display color and transparency of the voxel are set, the discharging unit discharges the colored liquid by an amount of liquid according to the display color, and discharges the achromatic colored liquids and the colorless transparent liquid by an amount of the liquids at a ratio according to the transparency, so that a remaining portion which is other than a portion filled with the discharged colored liquid among total capacity of the voxel is filled, and the curing unit cures the discharged colored liquid and the transparent liquid to form the voxels.

First claim

What is claimed is:

1 . A three-dimensional object formation apparatus comprising:
a discharging unit which discharges a plurality of achromatic colored liquids and a colorless transparent liquid; and a curing unit which cures a liquid discharged from the discharging unit to a formation table to form a voxel configuring a three-dimensional object on the formation table, wherein a display color and transparency of the voxel are set, the discharging unit discharges the colored liquid by an amount of liquid according to the display color, and discharges the achromatic colored liquids and the colorless transparent liquid by an amount of the liquids at a ratio according to the transparency, so that a remaining portion which is other than a portion filled with the discharged colored liquid among total capacity of the voxel is filled, and the curing unit cures the discharged colored liquid and the transparent liquid to form the voxels.

2 . The three-dimensional object formation apparatus according to claim 1 ,
wherein the discharging unit discharges the white liquid among the achromatic colored liquids and the colorless transparent liquid by an amount of the liquids at a ratio according to the set transparency.

3 . The three-dimensional object formation apparatus according to claim 1 ,
wherein the discharging unit discharges the colored liquids so that the remaining portion is formed in the voxel.

4 . A three-dimensional object formation method which is executed by a three-dimensional object formation apparatus including a discharging unit which discharges a plurality of achromatic colored liquids and a colorless transparent liquid, and a curing unit which cures a liquid discharged from the discharging unit to a formation table to form a voxel configuring a three-dimensional object on the formation table in which a display color and transparency of the voxel are set, the method comprising:
causing the discharging unit to discharge the colored liquid by an amount of liquid according to the display color, and discharge the achromatic colored liquids and the colorless transparent liquid by an amount of the liquids at a ratio according to the transparency, so that a remaining portion which is other than a portion filled with the discharged colored liquid among total capacity of the voxel is filled; and causing the curing unit to cure the discharged colored liquid and the transparent liquid to form the voxels.

5 . A three-dimensional object formation program executed by a control unit of a three-dimensional object formation apparatus including a discharging unit which discharges a plurality of achromatic colored liquids and a colorless transparent liquid, a curing unit which cures a liquid discharged from the discharging unit to a formation table to form a voxel configuring a three-dimensional object on the formation table, and the control unit which controls the discharging unit and the curing unit,
wherein a display color and transparency of the voxel are set, and the three-dimensional object formation program causes the control unit to execute: causing the discharging unit to discharge the colored liquid by an amount of liquid according to the display color, and discharge the achromatic colored liquids and the colorless transparent liquid by an amount of the liquids at a ratio according to the transparency, so that a remaining portion which is other than a portion filled with the discharged colored liquid among total capacity of the voxel is filled; and causing the curing unit to cure the discharged colored liquid and the transparent liquid to form the voxels.
