Abstract
Description
Technical Field

[0002] Digital Light Processing (DLP) is a technology that uses light curing technology to cure photosensitive polymer liquid layer by layer. It is widely used in the field of precision printing.
[0003] Segmented printing technology refers to printing the same product using different raw materials. Due to different parameters such as the solidification time of the raw materials, different printing speeds can be used. In other words, different segments in segmented printing will use different raw materials and match the appropriate printing speed.
[0004] Segmented printing technology is mostly used to print larger parts. At this time, if the printing page is replenished by relying solely on the flow of solution, the printing interval will be lengthened, resulting in reduced printing efficiency. Summary of the Invention
[0005] The present application provides a DLP-3D batch printing system based on segmented printing control, which uses the method of actively constructing liquid printing pages to shorten the printing interval and improve printing efficiency.

[0031] The technical solution in this application is further described in detail below with reference to the accompanying drawings.
[0032] The present application discloses a DLP-3D batch printing system based on segmented printing control. In some examples, the DLP-3D batch printing system based on segmented printing control disclosed in the present application includes a printing pool 11, a lateral moving platform 12, a lifting platform 13, a printing module 14 and a solution filling module 2. Figure 1 There are multiple printing pools 11, which are arranged sequentially in the horizontal direction or the vertical direction of the horizontal plane, and the horizontal moving platform 12 is set parallel to the arrangement direction of the printing pools 11.
[0033] See also Figure 2 The lifting platform 13 and the printing module 14 are both installed on the transverse moving platform 12. The lifting platform 13 is located above the printing pool 11, and the printing module 14 is located below the printing pool 11. The lifting platform 13 and the printing module 14 can switch between different printing pools 11 along with the transverse moving platform 12.
[0034] The solution filling module 2 is disposed on the printing pool 11 , and is used to lay a solution layer in the printing pool 11 . Here, the printing pool 11 can contain the same solution or different solutions.
[0035] It should be understood that in the printing method used in this application, the printing module 14 is deployed below the printing pool 11, and the light (specified area) generated by the printing module 14 will cause the solution in the printing pool 11 to solidify. The solution in the printing pool 11 solidifies layer by layer, which is the DLP-3D printing technology mentioned above.
[0036] The existing DLP-3D printing technology (upper fixation method) is to immerse the printed part directly in the solution and then solidify it layer by layer (layer printing). This method can only achieve a fast printing speed when printing micro parts. For larger parts, the flow rate of the solution will cause the efficiency of layer printing to decrease.
[0037] The solution used in this application is to deploy multiple printing pools 11, each printing pool 11 provides a thinner solution layer, which can quickly form a solution layer with printing conditions between the part and the bottom surface of the printing pool 11.
[0038] Furthermore, when switching printing materials, thinner solution layers are easier to clean because only a small amount, or even a trace amount, of solution remains on the part. If immersion printing is used, more solution will inevitably remain on the part, especially for hollow parts. If the residual solution is excessive and distributed over a wide range of heights, it will be very troublesome to clean.
[0039] If the method for controlling the thickness of the solution layer provided in this application is used, this problem can be better solved because this method effectively controls the height range of the residual solution.
[0040] In some examples, there are two transverse moving platforms 12 , and the two transverse moving platforms 12 are symmetrically arranged on both sides of the printing pool 11 , so that the printing pool 11 can simultaneously support two parallel printing processes.
[0041] See also Figure 3 In some possible implementations, a partition wall 15 is provided in the middle of the printing pool 11. The partition wall 15 can divide the space inside the printing pool 11 into two independent parts, respectively providing support for two parallel printing processes.
[0042] See also Figure 1 and Figure 4 In some examples, the solution filling module 2 includes a first linear module 21, a lifter 22, a feeding workbench 23, a grid 24, a feeding tube 25 and a recovery tube 26, the first linear module 21 is deployed between two adjacent printing pools 11, and the lifter 22 is set on the first linear module 21.
[0043] The feeding workbench 23 is installed on the lifter 22. The first linear module 21 is responsible for the horizontal movement of the feeding workbench 23, and the lifter 22 is responsible for the vertical movement of the workbench 23, so as to move the feeding workbench 23 into the printing pool 11 and move the feeding workbench 23 out of the printing pool 11.
[0044] The grid 24 is set on the working surface of the feeding workbench 23. At the same time, there is a distance between the grid 24 and the working surface of the feeding workbench 23. The function of the grid 24 is to divide the space inside the printing pool 11 into multiple independent subspaces.
[0045] The purpose of dividing the independent subspace is to reduce the flow range of the solution so that the solution height in each independent subspace can be consistent.
[0046] The feeding tube 25 and the recovery tube 26 are arranged in an array on the working surface of the feeding workbench 23. The function of the feeding tube 25 is to feed the solution into multiple independent subspaces in the printing pool 11, and the function of the recovery tube 26 is to retrieve excess solution.
[0047] The first end of the feed pipe 25 and the first end of the recovery pipe 26 are both directed toward the grid 24. The second end of the feed pipe 25 and the second end of the recovery pipe 26 are respectively connected to corresponding terminal devices. The second end of the feed pipe 25 is connected to the feed pump, and the second end of the recovery pipe 26 is connected to the recovery pump. Both the feed pump and the recovery pump are connected to the material tank.
[0048] When the feeding pipe 25 is feeding, the feeding height will be higher than the height of the grid 24.
[0049] In some possible implementations, the first end of the feeding tube 25 extends into the interior of the grid 24 .
[0050] In some possible implementations, the first end of the recovery pipe 26 abuts against the top surface of the grid 24 .
[0051] Furthermore, the first end of the recovery pipe 26 is a closed end, and a through hole is provided on the side surface of the first end of the recovery pipe 26, such as Figure 5 shown.
[0052] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
