Three-dimensional full color composite printing device

The present invention relates to a three-dimensional full-color composite printing device, and more particularly to a three-dimensional full-color composite printing device suitable for a three-dimensional rapid prototyping machine.

3D Printing molding technology, also known as Rapid Prrototyping (RP) technology, is fast, straightforward and fast, and can accurately transform design ideas into functional prototypes or can be manufactured. Directly used parts or finished products, which can quickly evaluate, modify and test the product design, greatly shortening the product development cycle, thus making 3D printing technology popular.

Today's 3D printing and forming technology is in a booming stage, and the rapid prototyping technology used is also different. The rapid prototyping technology currently used in the industry mainly includes the following technologies: Color-Jet Printing , CJP, or Binder Jetting technology, Fused Deposition Modeling (FDM) technology, Stereo Lithography Apparatus (SLA) technology, UV-curable liquid resin molding (Multi-Jet Modeling, MJM) Technology, or Selective Laser Sintering (SLS) technology, etc., but not limited to this.

However, in the above rapid prototyping technology, except for the color-Jet Printing (CJP, or Binder Jetting) technology, which can produce full-color 3D moldings, the other 3D printing and molding technologies cannot be manufactured. Full-color products, therefore, for the 3D printing technology known as the third industrial revolution, is a lack of great product technology, no real full-color products, meaning that human technology returns to a color performance The era of restrictions is a fatal flaw for the 3D printing industry.

This technical bottleneck is mainly because the 3D printing and forming technology utilizes the base layer stacking technology, that is, as shown in Fig. 1, when the 3D molding A is to be manufactured, the main type is first to analyze the type and structure of the A through the computer. The plurality of laminates are divided into A's, and then the laminates indicated by A' are printed in the axial direction of XY by layer-by-layer printing and stacking by the above-mentioned 3D printing and forming techniques. The layers are stacked again so that they are stacked in the Z direction, and finally a semicircular 3D molding as shown in A is formed. Similarly, if the 3D molding B of the conical flask shape shown in Fig. 2 is to be formed, B is also divided into a plurality of laminations shown by B', and then layer-by-layer printing and stack molding are performed to manufacture. A 3D molding B of a conical shape is obtained. However, in many 3D printing and molding technologies, it is impossible to make full-color 3D products, mainly when stacking layer by layer, lacking a print head corresponding to full-color technology.

For example, the conventional Stereo Lithography Apparatus (SLA) technique generates a polymerization reaction on a thin layer of a liquid UV curable resin by irradiating with a UV light source and along each layered cross-sectional profile. The thin layer of the liquid UV curable resin is cured and then stacked layer by layer. However, in the UV-curable liquid resin molding process, since the liquid UV-curable resin as a molding material is a single color, and in the process of curing by UV light irradiation and layer-by-layer stacking, no device can implement full color. Because of the printing operation, the 3D molded product produced by this SLA technology can only maintain the original color of the original liquid UV curing resin, and cannot produce a full-color 3D product.

Therefore, as far as the industry of 3D printing technology devices is concerned, the technical bottleneck faced by them is the full color performance problem. Therefore, how to make this fatal prior art defect can be improved is the current 3D printing and molding industry. The main subject that is urgently needed to be solved.

The main purpose of this case is to provide a 3D printing full-color 3D full-color composite printing device, which is applied to the Stereo Lithography Apparatus (SLA) technology to implement full color 3D printing.俾 can solve the technical bottleneck that many 3D printing and molding technologies cannot produce full color.
