Multifunctional composite printing device

Abstract

The invention relates to a multifunctional composite printing device. The device comprises a housing, a heating assembly, multiple types of colored printing ink and ink jet chips, wherein the housing has a plurality of cavities; the heating assembly is arranged in one of the cavities of the housing, and is provided with an extrusion port; the multiple types of colored printing ink are accommodated in other cavities of the housing, respectively; the ink jet chips are arranged correspondingly on the bottom surface of the housing and have a plurality of jet holes which communicate with the colored printing ink, and being driven by the ink jet chips, the colored printing ink is sprayed; after macromolecular materials are conveyed to the heating assembly in the housing, the macromolecular materials are heated and fused through the heating assembly and then are extruded by the extrusion port, and the colored printing ink is sprayed at a predetermined time through the jet holes of the ink jet chips, so that the colored printing ink is attached to the fused macromolecular material microdroplets to form colored macromolecular material microdroplets so as to be stacked and cured to form a full-colored three-dimensional formed substance.

Description

[0001] 【Technical field】 [0002] The invention relates to a multifunctional composite printing device, especially a multifunctional composite printing device suitable for a three-dimensional rapid prototyping machine. [0003] 【Background technique】 [0004] 3D printing (3D Printing) prototyping technology, also known as Rapid Prototyping (RP) technology, because rapid prototyping technology is automatic, direct and fast, it can accurately transform design ideas into prototypes with certain functions or can be manufactured directly for use The parts or finished products can be quickly evaluated, modified and functionally tested on the product design, which greatly shortens the product development cycle, thus making 3D printing molding technology widely favored. [0005] Today's 3D printing molding technology is in a stage of vigorous development, and the rapid prototyping technologies used are also different. The rapid prototyping technologies currently used in the industry ma...

Problems solved by technology

However, in this SLS technology, since the solid molding raw material powder has only a single color, and there is no device that can perform full-color inkjet printing in the process of layer-by-layer stacking, the 3D printing produced by SLS technology The molding can only maintain the original color of the original solid molding raw material powder, but cannot produce a full-color 3D molding

[0013] Looking at the aforementioned known technologies, neither FDM, SLA, MJM, nor SLS can produce full-color 3D moldings.

[0014] Therefore, as far as the current industry of 3D printing and molding technology installations is concerned, the technical bottleneck it faces is the problem of full-color display. Therefore, how to improve this fatal lack of previous technology is an urgent issue in the current 3D printing and molding industry. Main issues to be addressed
