Three-dimensional full color composite printing apparatus

Abstract

The invention relates to a three-dimensional full color composite printing apparatus. The apparatus comprises: a plurality of shells comprising at least one cavity, wherein one separation shell and other shells are separately arranged on at least one displacement mechanism; a light source assembly arranged in the cavity of the separation shell; liquid resins arranged in the cavities of the other shells; inks, wherein the inks with different colors are respectively accommodated in the other cavities of the other shells; a plurality of inkjet chips arranged on the bottom surface of the other shells and provided with a plurality of jet holes; and molding pallets arranged on a lifting platform to carry out Z-direction displacement, wherein the inkjet chips spray the liquid resins on the molding pallets, colored inks are jet by the other inkjet chips and are attached to the liquid drops of the liquid resin, the obtained liquid drops are irradiated by the light source assembly to realize solidification molding, and a plurality of stack layers are formed through repeated construction in order to complete full color three-dimensional moldings.

Description

[0001] 【Technical field】 [0002] The invention relates to a three-dimensional full-color composite printing device, in particular to a three-dimensional full-color 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 c...

Problems solved by technology

However, similar to the above-mentioned many known technologies, in this MJM technology, since the liquid resin is also a single-color raw material, it can only produce a single color after printing through the nozzle and curing with ultraviolet light. 3D moldings, there is no device for full-color inkjet printing, so the 3D moldings produced by MJM technology can only maintain the original color of the original liquid resin, and it is also impossible to produce full-color 3D products

[0009] 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 3D printing and molding industry. Main issues to be addressed
