Multifunctional composite printing device

The present invention relates to a multifunctional composite printing device, and more particularly to a multifunctional composite printing device suitable for a stereo 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, as shown in FIG. 3, the conventional molding apparatus 1 of a Fused Deposition Modeling (FDM) machine mainly has two bodies 10, a plastic wire 11, a support wire 12, two driving wheels 13, and two liquefaction. The structure of the two heating elements 15 and the like, as shown in the figure, the two bodies 10 are respectively used for supporting materials such as the plastic wire 11 and the supporting wire 12, and the plastic wire 11 and the supporting wire 12 are fine plastic wires. And the like, but not limited thereto, and the plastic wire 11 and the support wire 12 are respectively sent to the two heating assemblies 15 via the two driving wheels 13 and the liquefier 14, respectively, and the plastic wire 11 and the supporting wire 12 are respectively transmitted through the heating assembly 15. Heating to a temperature higher than the melting point to melt, and then extruding the molten plastic material and the supporting material from the extrusion port 15a of the heating assembly 15 which can control the displacement in the XY direction, so that the molten plastic material and the supporting material are The cold bottom layer is attached, and the cross-sectional shape is drawn, and the plastic material and the supporting material of the molten material can be naturally cooled and solidified in an instant, and sequentially stacked and formed, so that the 3D molding is stacked layer by layer. .

However, the color of the 3D molded product formed by this FDM technique is mainly determined by the color of the plastic wire 11 supplied to the FDM device at that time, and because only the single color plastic wire 11 is melted and constitutes a 3D molded product. The overall structure is that it is impossible to produce a full-color 3D molded product by this FDM technique.

In addition to the aforementioned FDM technology, another Steero Lithography Apparatus (SLA) technique is to irradiate a liquid UV curable resin layer by irradiating it with a UV laser source and along various cross-sectional profiles. A polymerization reaction is generated to cure the thin layer of the liquid UV curable resin, and then stacked in layers. However, in the UV-curing liquid resin molding process, since the liquid UV-curable resin as a molding material is a single color, and in the process of curing and layer-by-layer stacking by UV laser irradiation, 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-curable resin, and cannot produce a full-color 3D molded product.

In addition, another conventional 3D printing and forming technology is a multi-Jet Modeling (MJM) technology, which mainly uses a nozzle to print a liquid resin and a liquid supporting material, and then The layered cured structure is formed by irradiating with ultraviolet light (UV) to cure the liquid resin and the support material, and is further layered to form a 3D molded product. However, similar to many of the above-mentioned conventional techniques, in the MJM technology, since the liquid resin is also a single color material, it is still only capable of producing a single color after being printed through a nozzle and cured by ultraviolet light. 3D moldings, there is no device to carry out full-color printing operations, so the 3D moldings produced by MJM technology can only maintain the original color of the original liquid resin, and can not produce full-color 3D molding. Things.

In another example of the conventional 3D printing technology, the Selective Laser Sintering (SLS) technology is mainly used to layer the raw material powder and use the laser light in a molding tank. The scanning and sintering are performed according to the layered profile profile, so that the temperature of the molding raw material powder is raised to the melting point, so that the molding raw material powder is adhered into a layered structure, and stacked into a 3D molding. However, in this SLS technology, since the solid molding raw material powder has only a single color, and in the process of layer-by-layer stacking, there is no device capable of performing full-color printing, so the 3D produced by the SLS technology. The molded product can only maintain the original color of the original solid molding raw material powder, and cannot produce a full-color 3D molded product.

Looking at the above-mentioned various conventional techniques, it is impossible to manufacture a full-color 3D molded product regardless of FDM technology, SLA technology, MJM technology or SLS technology.

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 multi-functional composite printing device capable of implementing full-color 3D printing, which is applicable to both fused deposition (FDM) technology, laser sintered liquid resin molding (SLA) technology, and ultraviolet light. 3D printing can be implemented in 3D printing and forming machines such as solidified liquid resin molding (MJM) technology or laser sintered solid powder molding (SLS) technology, which can solve many current 3D printing and molding technologies. It is impossible to create a technical bottleneck for full color.
