The Algorithm and Application of Fast Surface Slice and Color Acquisition for Color 3D Printing

The production of color 3D printing technology for large building decoration parts is much more efficient than artificial sculpture. But based on special requirements, the surface of the printed object can have color. And the current commonly used 3D printing technology printed objects is no color requirements. Therefore, the large building decoration color 3D printing needs to obtain the color information of the model surface. This paper proposes a fast slice and color acquisition algorithm for the 3D model, first converting the model surface triangle into triprisms with printing thickness to form the surface color area, then obtains the color information coordinate formula using the model triangle topology, and calculates the color information coordinates of adj acent pixels for color 3D printing. Experimental results show that the proposed algorithm achieves the desired purpose, high efficiency, good versatility and wide application.
