Colorful printing mechanism of 3D printer

Abstract

The invention discloses a colorful printing mechanism of a 3D printer. The colorful printing mechanism of the 3D printer is composed of printing cooling fans, a fan support, a temperature control fusion extrusion component, a fixing plate, feeding pipes, four-color feeding motor devices, a colorful material extruding nozzle cooling fan and a colorful material extruding nozzle. The 3D printing mechanism further comprises a microprocessor control device, an X-axis moving device, a Y-axis moving device, an X-axis hierarchical moving module, a Y-axis hierarchical moving module, a 3D color module, a hierarchical decomposition module, a four-color segmentation value calculating module and a four-color feeding speed value generating module. By the adoption of the colorful printing mechanism, four standard colors are adopted, the four-color feeding motor devices control the feeding ratio of the four standard colors so as to achieve the purpose of making different colors through mixing, a user just needs to buy the consumables of cyan, magenta, yellow and black, and colorful objects in any shape can be directly generated from computer graphic data. Therefore, the production period of products is greatly shortened, the production efficiency is improved, and the manufacturing cost is lowered.

Description

technical field [0001] The invention relates to the field of printing technology, in particular to a multi-color printing mechanism of a 3D printer. Background technique [0002] The 3D printing technology based on fused deposition modeling (Fused Deposition Modeling, hereinafter referred to as FDM) first appeared in the 1980s. Its working principle is to generate 3D entities by adding materials layer by layer. , scanning, etc. to obtain the three-dimensional model of the object to be printed, and then complete a series of digital slices along a certain direction through computer-aided design technology, and transmit the information of these slices to the 3D printer, and the computer generates machine instructions based on the digital slices. The 3D printer prints thin layers according to the machine instructions, and stacks successive thin layers until a solid object is formed to form a three-dimensional object, and finally 3D printing is completed. At present, FDM 3D prin...

Problems solved by technology

At present, FDM 3D printers are limited to single-color printing. Although multi-color printing can be achieved by changing printing materials, the process is very complicated and time-consuming, but the required colors must be customized in advance, and the printed color quality is not high.

In order to obtain colorful prints, users must customize more than ten printing materials of different colors at the same time. During the printing process, the printing materials of the required colors need to be replaced manually; and the current full-color 3D model printing technology also includes three-dimensional printing (Three-Dimensional printing) Printing (hereinafter referred to as 3DP), Stereo Lithography Apparatus (hereinafter referred to as SLA) and Laminated Object Manufacturing (hereinafter referred to as LOM) technologies, however, for the cost of these three types of technologies, whether it is 3D models or 3D Printer-wise, it's all very expensive
