Abstract

An image processing device includes a data receiver to receive three-dimensional object data of an object and a circuitry to create three-dimensional data from the three-dimensional object data when coloring at least part of a surface of the object, to conduct the coloring to the outer layer of the surface and multiple inner layers of the object.

Claims

1. An image processing device comprising:

a data receiver to receive three-dimensional object data of an object; and

a circuitry to create three-dimensional data from the three-dimensional object data when coloring at least part of a surface of the object, to conduct the coloring to an outer layer of the surface and multiple inner layers of the object.

2. The image processing device according to claim 1, wherein the outer layer and the multiple inner layers are adjacent to each other.

3. The image processing device according to claim 1, wherein thickness of the outer layer and the multiple inner layers is not less than 50 μ

m.

4. The image processing device according to claim 1, wherein at least one layer of the multiple inner layers has a dot arrangement pattern different from that of the outer layer.

5. The image processing device according to claim 4, wherein the three-dimensional data are created by using three dimensional dithermatrix that regulates dot arrangement.

6. The image processing device according to claim 4, wherein the three-dimensional data are created by an error diffusion method using a three-dimensional weight matrix.

7. The image processing device according to claim 4, wherein the three-dimensional data are created by changing noise positions that generates a random pattern for each of the multiple inner layers.

8. The image processing device according to claim 4, wherein the three-dimensional data are created by at least rotating or parallel-shifting the dot arrangement pattern for each of the multiple inner layers.

9. An image processing system comprising:

the image processing device of claim 1; and

an additive manufacturing device to manufacture the object based on the three-dimensional data created by the image processing device.

10. A non-transitory recording medium storing a plurality of instructions which, when executed by one or more processors, cause the processors to perform a control method of an image processing device, comprising:

receiving three-dimensional object data of the object; and

creating three-dimensional data from the three-dimensional object data when at least part of a surface of the object is subject to coloring, which is applied to an outer layer of the surface and multiple inner layers of the object.

11. A method of manufacturing an object comprising:

receiving three-dimensional object data of the object;

creating three-dimensional data from the three-dimensional object data when coloring at least part of a surface of the object, to conduct the coloring to an outer layer of the surface and multiple inner layers of the object; and

manufacturing the object based on the three-dimensional data.
