Three-dimensional full-color composite printing device

Abstract

The invention relates to a three-dimensional full-color composite printing device which is applicable to forming a liquid resin forming article and comprises a plurality of housings, a light source component, color inks, ink jet chips and a forming tray, wherein each housing is provided with at least one empty chamber; the separation housing and the other housings are separately constructed on at least one displacement mechanism; the light source component is arranged in the empty chamber of the separation housing; the color inks are contained in the empty chambers of the other housings; the ink jet chips are arranged on the bottom surfaces of the other housings, provided with a plurality of jet orifices and communicated with the color inks; the forming tray is constructed on a lifting platform to move in a Z direction, and carries and supports liquid resin droplets solidified due to illuminating of the light source component; the color inks are ejected from the jet orifices onto the solidified droplets to form a single section layer of a three-dimensional forming article; the procedure is repeated to construct a plurality of stack layers; and finally, the full-color three-dimensional forming article is solidified and formed.

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, in the molding process of this UV light-curable liquid resin, since the liquid UV-curable resin used as the molding material is a single color, and in the process of curing and layer-by-layer stacking with UV light irradiation, there is no device that can implement full-color printing. Therefore, the 3D moldings produced by this SLA technology can only maintain the original color of the original liquid UV curable resin, and cannot 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
