Description

Rapid prototyping device 【0001】

The present invention relates to a rapid prototyping device, and more particularly to a rapid prototyping device having a two-dimensional object printing module and a three-dimensional object printing module.

【0002】

Rapid Prototyping (RP technology) is developed based on the concept of constructing pyramid-like layer stacking. The main technical feature is the rapid molding, which can be used without any tools, molds and fixtures. Automatically and quickly convert any complex shape design into a three-dimensional solid model, which greatly shortens the development cycle of new products and reduces development costs. It can ensure the time-to-market of new products and the success rate of new product development. Technology provides a more complete and convenient product design communication tool between technicians and non-technical personnel such as technicians and corporate decision makers, product users, etc., thus significantly improving the competitiveness of products in the market and enterprises. Rapid response to the market.

[0003]

With the development of rapid prototyping technology, rapid prototyping methods capable of producing 3D solid models have also developed in many ways, such as: 3-D Printing (3-DP), Stereo-Lithography (SLA), and selection. Selective Laser Sintering (SLS), Solider Process (SP), Fused Deposition Modeling (FDM), and Laminated Object Manufacturing (LOM). Among them, the three-dimensional object printing operation still includes the general rapid prototyping printing operation, the main process of which is to first spread the material, spray the bonding agent on the paving material, wait for the binder to dry, remove the residual material, and re-lay the material... Layered and stacked to form a three-dimensional object, however, in this process, whether it is paving, printing or waiting for the adhesive to dry, remove the residual material, etc., it takes time, and each step of the stack needs to repeat the above steps. Therefore, if a traditional three-dimensional object is used for printing, it takes more than 10 hours to complete the manufacturing time of a three-dimensional object, which is quite time consuming and labor-intensive.

[0004]

In addition, if the three-dimensional object is laminated by the lamination method, the conventional method firstly confirms the contour of the three-dimensional object to be formed by computer drawing, and then prints the laser light according to the contour drawn by the computer. The medium is precisely cut, and the printing medium is stacked through layers. Each layer of printing medium needs to perform a precise laser cutting, and then the material is cut after the cutting is completed, so as to complete the forming of the three-dimensional object. However, in the conventional lamination process, since the precise cutting operation of the laser is required, the manufacturing cost is relatively high, and it takes a lot of time to perform the relevant cutting operation, and since each layer of the printing medium is required to pass through The precise cutting of the laser makes it easy to increase the temperature around the device, and it is necessary to pay attention to the safety measures of the working environment around the device.

[0005]

In view of this, how to develop a rapid prototyping device that can simultaneously form a two-dimensional object printing module and a three-dimensional object printing module in the same device, can solve the printing problem at one time, which is currently There is an urgent need to solve the problem.

[0006]

The main purpose of the present invention is to provide a rapid prototyping device, which can have a two-dimensional object printing module and a three-dimensional object printing module in the same device, and solve the problem that the rapid prototyping device is slow in forming. problem.

It is mainly used to perform a specific size cutting operation on the printed sheet medium 14, and the stacked material collecting groove 121 is used to collect the cut sheet medium 14. For example, when the two-dimensional object printing module 13 of the embodiment performs the two-dimensional object printing operation, the two-dimensional object printing mechanism 11 and the sheet medium 14 are used to complete the single-feeding two-dimensional object spraying. The printing operation, that is, the supply of the sheet medium 14 to the construction platform 17 through the medium supply mechanism 10, and the printing of a predetermined area of the sheet medium 14 by the printing mechanism 11 to print out the printing of the demand. In the drawing, the stacked sheet medium 14 of the subsequent stacked layer processing mechanism 12 can be used to collect the printed sheet medium 14 to complete the single-feed two-dimensional object printing operation.

[0013]

However, the two-dimensional object printing module 13 of the present invention can not only perform a two-dimensional object printing operation, but also can perform a three-dimensional object printing operation, so when the single-sheet medium 14 is a polymer film, a plastic film, a ceramic film, A metal film or a wood film, etc., when one of the materials and the paper material is laminated, it can perform a three-dimensional object printing operation of the single-sheet medium 14, as also shown in FIGS. 1A and 1B.

[0015]

As for the liquid etching and stripping device (not shown), the hot-pressed three-dimensional object superimposing and stacking module can be subjected to an etching process or a rinsing process, and since the printing material in the three-dimensional object superimposing and stacking module is a polymer film material, The three-dimensional object superimposing and stacking module after the hot compacting operation can be used to peel off the residual material by liquid rinsing or etching, and then the embryo of the three-dimensional shaped object is taken out. In addition, in the above-mentioned post-treatment and material removal operation, since the embryo of the three-dimensionally formed object has large capillary pores on its surface and inside, the strength characteristics thereof are weak, and the present invention can also be used in post-treatment and material removal operations. Further, the filling, infiltration and sintering strengthening operation is further carried out, and the coating and impregnation of the initial processing component of the three-dimensionally formed article is performed to infiltrate and fill the capillary pores, and then the final high-temperature sintering is performed by the sintering device to complete the forming of the strengthened hardness. operation. Of course, the above-mentioned post-processing workflows may be changed according to actual implementation conditions, and are not limited thereto.

[0016]
