Description

Two-dimensional or three-dimensional object jet printing method, fast jet printing device

【Technical field】

The present invention relates to a rapid jet printing device, in particular to a rapid jet printing device and a jet printing method capable of implementing two-dimensional object jet printing and three-dimensional object jet printing in the same device.

【Background technique】

Rapid prototyping technology (RP technology for short) is developed based on the concept of building a pyramid-like layer stacking molding. Automatically and quickly convert the design scheme of any complex shape into a three-dimensional solid model under any circumstances, which greatly shortens the research and development cycle of new products and reduces the cost of research and development, and can ensure the time to market of new products and the first-time success rate of new product development. Molding technology provides a more complete and convenient product design communication tool for technical personnel, as well as between technical personnel and enterprise decision makers, product users and other non-technical personnel, thus significantly improving the competitiveness and competitiveness of products in the market. The ability of enterprises to respond quickly to the market.

With the development of rapid prototyping technology, rapid prototyping methods that can produce three-dimensional solid models have also developed in multiple ways, such as: three-dimensional printing (3-D Printing, 3-DP), stereolithography (Stereo-Lithography, SLA), selective Laser sintering (Selective Laser Sintering, SLS), three-dimensional plate making (Solider Process, SP), hybrid deposition modeling (Fused Deposition Modeling, FDM), and lamination method (Laminated Object Manufacturing, LOM), etc. Among them, in the traditional 3D printing operation, the main process is to spread the material first, spray the adhesive on the material, wait for the adhesive to dry, remove the remaining material, and then spread the material again... In this way, a three-dimensional Objects, however, in this process, whether it is laying materials, spray printing, or waiting for the adhesive to dry, removing the remaining materials, etc., it takes time, and the above steps need to be repeated for each layer stacked, so if Using traditional 3D printing operations, it often takes more than 10 hours to complete the manufacture of a 3D object, which is quite time-consuming and labor-intensive.

In addition, if the layered construction of the three-dimensional object is carried out by the lamination method, the traditional method first uses computer drawing to confirm the outline of the three-dimensional object to be formed, and then uses the laser to print the printing medium according to the outline drawn by the computer. Precise cutting is performed by stacking the printing media layer by layer. Each layer of printing media needs to be precisely cut by laser, and after the cutting is completed, the material removal operation is performed, so as to complete the forming of the three-dimensional object. However, in the traditional sheet lamination process, because of the need for precise laser cutting, its manufacturing cost is relatively high, and it takes a lot of time to perform related cutting operations, and because each layer of printing media must pass through The precise cutting of the laser will easily increase the temperature around the device, and it is necessary to pay extra attention to the safety measures of the working environment around the device.

In addition, whether it is to use the traditional 3D object printing operation or the lamination method for the construction of 3D objects, it is usually only implemented for 3D objects, and it is not possible to print 2D objects in the same device. In this way, the rapid prototyping device for three-dimensional objects is separated from the traditional two-dimensional object printing device, which limits its applicability.

Please refer to FIG. 3A and FIG. 3B , which are respectively a schematic diagram of a rapid jet printing device and a partial cross-sectional structure diagram of the rapid jet printing device according to a second preferred embodiment of the present invention. As shown in Figure 3A, the rapid jet printing device 3 of the present embodiment also includes a medium supply mechanism 30, a jet printing mechanism 31, and a stacking layer processing mechanism 32, and the jet printing mechanism 31 and the stacking layer processing mechanism 32 are arranged in a working On the platform 33, similar to the foregoing embodiments, the medium supply mechanism 30 is used to supply the sheet medium 4, the spray printing mechanism 31 implements the spray printing operation to a predetermined area (not shown) of the sheet medium 4, and the stacking processing mechanism 32 Then, a cutting operation of a specific size is performed on the printed sheet medium 4 , but in this embodiment, the medium supply mechanism 30 mainly supplies the sheet medium 4 in the manner of supplying a single piece of medium.

Please refer to FIG. 3B , as shown in the figure, the medium supply mechanism 30 includes a carrier plate 300, a feed guide wheel 301, and a heat pressing roller 302, wherein the carrier plate 300 is used to carry the sheet medium 4, and the sheet medium 4 can be made of polymer Film, plastic film, ceramic film, metal film or wood film...

In this embodiment, the spray printing mechanism 31 is a print head printing platform 310, which is mounted on the working platform 33, and is movable or non-movable. Similar to the foregoing embodiments, the print head printing platform 310 can be a two-dimensional print head independent platform structure (as shown in FIG. Print platform architecture (as shown in Figure 2B).

After each sheet medium 4 is cut, the lifting platform 322 will reduce the thickness of a sheet medium 4, so that the new sheet medium 4 is cut, and make it fall on the lifting platform 322 of the laminated material collection tank 321 for stacking and collecting ; and the stacking layer cutting member 320 can simply cut the passing sheet medium 4 into modules of the required size, and at the same time, when implementing the stacking layer operation of three-dimensional object jet printing, the cutting module is larger than the forming The spray printing outline of the object, so there is no need for precise cutting, and the sheet medium 4 that is newly transported to the top of the stack collection tank 321 is pushed continuously, and it falls into the lifting platform 322 of the stack collection tank 321 for cutting Cutting, and at the same time of cutting, the new sheet medium 4 can be superimposed on the cut sheet medium 4 to carry out the stacking operation, so as to form a three-dimensional object stacking stacking module. In some other embodiments, when performing general two-dimensional object printing, the size of the cutting module stacked with the laminated cutting member 320 is the size of the printing range required by the general sheet medium 4, but not based on this limit.

When the aforementioned three-dimensional object stacking and laminating module is completed, the remaining materials after the cutting operation of the three-dimensional object stacking and laminating module can be removed through post-processing.
