Color three-dimensional printing method and three-dimensional printing equipment

Abstract

A color three-dimensional printing method and three-dimensional printing equipment are provided, which are suitable for manufacturing a three-dimensional object according to a three-dimensional model.A slicing processing is performed on a 3D model to obtain a printing path file and a plurality of inkjet images. A first layer controlling data in the printing path file is read, wherein the first layer controlling data records a plurality of printing position points and a plurality of inkjet position points. Movement of a printing head is controlled according to the printing position points, andthe printing head is controlled to extrude a forming material, to establish a first layer object. A first inkjet image among the inkjet images is read. Movement of an inkjet head on a plane is controlled according to the inkjet position points, and the inkjet head is controlled to spray the ink on the first layer object according to the first inkjet image.

Description

technical field [0001] The invention relates to a printing method, in particular to a color three-dimensional printing method and three-dimensional printing equipment. Background technique [0002] With the advancement of Computer-Aided Manufacturing (CAM), the manufacturing industry has developed three-dimensional printing technology, which can quickly produce the original design concept. Three-dimensional printing technology is actually a general term for a series of rapid prototyping (RP) technologies. The coordinates discontinuously make the displacement of the thickness of the layer, and finally form a three-dimensional object. Three-dimensional printing technology can have unlimited geometric shapes, and the more complex the parts, the more the excellence of RP technology can be shown, and it can also greatly save manpower and processing time. Under the shortest time requirement, 3D computer-aided design (Computer-Aided Design, The digital three-dimensional model des...

Problems solved by technology

However, the color pigments of the former are only attached to the outer surface of the three-dimensional object, and its color rendering and variability are slightly insufficient

On the other hand, the latter requires repeated replacement of molding wires of different colors to achieve a colorful effect, and the production efficiency of colorful three-dimensional objects is not ideal.
