Method and system for building painted three-dimensional objects
First Claim
Patent Images
1. A method of printing a three dimensional (3D) colored object, layer-by-layer, the method comprising:
- dividing apparent surface of the 3D object into 3D color cells, wherein each of the 3D color cells comprises a tangential area with respect to the apparent surface and a depth dimension directing toward the inner region of the object and the size of each color cell is determined according to a desired color spatial resolution and color shade resolution;
generating color patterns of basic colors, each pattern for a respective 3D color cell according to a desired color shade of the cell;
generating two-dimensional (2D) image data for layers of the 3D objects, wherein the 2D image data includes outline color data based on the color patterns; and
selectively depositing materials on successive layers based on the 2D image data to produce the 3D colored object.

Abstract
Embodiments of the invention are directed to a method for printing a painted three-dimensional object. Each layer of the object is printed so that only the external circumference of the layer contains colored material. The building material used may be transparent, and a white colored material may be used as a barrier between the building material and the colored material.
