Abstract

A three-dimensional object that maintains a satisfactory visual color quality when the object is observed at different positions or through different angles, and a three-dimensional shaping apparatus for and a three-dimensional shaping method of shaping such a three-dimensional object are provided. The three-dimensional object includes: a shaping base having a first and second outer surfaces adjacent to each other at an adjacent angle; a first colored layer formed on the first outer surface and including a transparent material colored in a first color; a second colored layer formed on the second outer surface and including a transparent material colored in a second color different from the first color; and a partition layer interposed between the side surfaces of the first colored layer and the second colored layer. The partition layer is opaque and has one of the first color, the second color, and an achromatic color.

a first colored layer formed on the first outer surface of the shaping base, the first colored layer including a transparent material colored in a first color;

a second colored layer formed on the second outer surface of the shaping base, the second colored layer including a transparent material colored in a second color different from the first color; and

a partition layer interposed between a side surface of the first colored layer and a side surface of the second colored layer, the partition layer being opaque and having one of the first color, the second color, and an achromatic color.

2. The three-dimensional object according to claim 1, wherein the side surface of the first colored layer makes a surface contact with the side surface of the second colored layer at a contact portion on an outer side in a thickness direction, and

the partition layer is disposed on an inner side in the thickness direction with respect to the contact portion.

3. The three-dimensional object according to claim 1, wherein the partition layer has a lower light transmittance than the first colored layer and the second colored layer.

4. The three-dimensional object according to claim 2, wherein the partition layer has a lower light transmittance than the first colored layer and the second colored layer.

5. The three-dimensional object according to claim 1, wherein the partition layer has a higher light transmittance as the adjacent angle has a greater degree.

6. The three-dimensional object according to claim 2, wherein the partition layer has a higher light transmittance as the adjacent angle has a greater degree.

7. The three-dimensional object according to claim 3, wherein the partition layer has a higher light transmittance as the adjacent angle has a greater degree.
