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.

Claims

1. A three-dimensional object comprising:

a shaping base having a first outer surface and a second outer surface adjacent to each other at an adjacent angle;

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,

wherein the partition layer has a lower light transmittance than the first colored layer and the second colored layer, and the partition layer is formed along a region where the first colored layer and the second colored layer are in surface contact,

wherein a natural light incident from an outside of the first colored layer or the second colored layer is shielded from transmission to an opposite side with respect to the partition layer and reflected.

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

4. 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.

5. The three-dimensional object according to claim 1, wherein the partition layer is provided only where the adjacent angle has a degree less than a threshold.

6. The three-dimensional object according to claim 2, wherein the partition layer is provided only where the adjacent angle has a degree less than a threshold.

7. The three-dimensional object according to claim 1, wherein the first outer surface and the second outer surface have an opaque achromatic color.

8. The three-dimensional object according to claim 2, wherein the first outer surface and the second outer surface have an opaque achromatic color.

9. The three-dimensional object according to claim 5, wherein the first outer surface and the second outer surface have an opaque achromatic color.

10. The three-dimensional object according to claim 7, wherein the first outer surface and the second outer surface have an opaque achromatic color.

11. The three-dimensional object according to claim 1, wherein the partition layer has an achromatic color close to white, gray, or has one of the first color and the second color.
