Problems solved by technology

The three-dimensional printing of the dual-nozzle has two feed ports, which can realize the mixed-color printing of the three-dimensional printing object. The color-mixing principle is: materials of different colors and physical properties are mixed together. The disadvantage is: because the color materials Residues at the place, unable to achieve rapid color change, only gradient
[0005] To sum up, no matter which of the above 3D printing methods is used, there is a problem that the color 3D printing cannot mix colors or the color mixing effect is not good.

Abstract

The invention discloses a colorful three-dimensional line printing method and device. When model line printing files of three-dimensional line printing objects are set, models of the three-dimensional line printing objects in different colors are layered to be provided with the layered line printing files, wherein corresponding color information and layer height information are set for the layered files; and the layered line printing files are integrated into the model line printing files of three-dimensional line printing objects, and are input into a three-dimensional line printing machine with multiple spraying heads for three-dimensional line printing. In this way, the beneficial effect of three-dimensional line printing of the multiple spraying heads of the three-dimensional line printing machine can be retained, and the shortcoming that color mixing cannot be achieved through one single spraying head is overcome. Furthermore, the manner of color mixing in the colorful three-dimensional line printing method and device is completely different from a manner of color mixing adopted by a dual-spraying-head three-dimensional line printing machine in the prior art; and as for the three-dimensional line printing objects, the colorful three-dimensional line printing color mixing effect is improved through stacking of layers in different colors and with different thicknesses specifically.

Description

technical field [0001] The invention relates to printing technology, in particular to a method and device for color three-dimensional printing. Background technique [0002] 3D printing is a form of additive manufacturing technology in which 3D printed objects are created by a 3D printer through successive physical layers. Compared with other additive manufacturing technologies, the three-dimensional printing machine has the advantages of fast speed, low price and high usability. A three-dimensional printing machine is a device that can print out real three-dimensional objects. It is functionally the same as the laser forming technology. It adopts layered processing and superposition forming, that is, the three-dimensional printing object is generated by adding materials layer by layer, which is different from the traditional removal Material processing techniques are completely different. It is called a three-dimensional printing machine because it refers to its technical...
