Multifunctional composite printing device

Abstract

The invention provides a multifunctional composite printing device which is suitable for formed substances of formed granular powder. The multifunctional composite printing device comprises a housing, a light source device, multiple types of colored printing ink and ink jet chips, wherein the housing is provided with a plurality of cavities; the light source device is arranged in one of the cavities of the housing so as to provide a laser light source; each type of the colored printing ink is accommodated in one of the 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 to the granular powder, and as a result of the repeated action, a full-colored three-dimensional formed substance is finally cured and formed.

Description

[0001] 【Technical field】 [0002] The invention relates to a multifunctional composite printing device, in particular to a multifunctional composite printing device suitable for a three-dimensional rapid prototyping device. [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 indust...

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 the SLS technology The molding can only maintain the original color of the original solid molding raw material powder, but cannot produce full-color 3D products

[0013] Looking at the aforementioned known technologies, it is impossible to manufacture full-color 3D products with FDM technology, SLA technology, MJM technology or SLS technology.

[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
