Description

Technical Field

[0001] The utility model belongs to the technical field of additive manufacturing, and specifically relates to a sunken light-curing 3D printing flexible glue pool. Background Art

[0002] In the light-curing 3D printing device and method, photopolymerizable liquid slurry (such as resin, ceramic and polymer material) is used as the printing material. In order to achieve layer-by-layer printing, the glue tank is responsible for containing these materials so that the printing device can obtain the required printing materials from them. This process directly affects the final size and processing accuracy of the 3D printed structure, so the glue tank is a key hardware component in the light-curing 3D printing device.

[0003] In the photocuring 3D printing glue pool, objects are usually printed from the bottom up. The printing stage moves upward and the printed object is extracted from the glue pool in an inverted form. Although the glue pool structure is simple in design, when printing large and heavy objects, gravity may cause the printed object to fall off the stage and be damaged. Even though the top-down printing method can effectively improve the success rate of printing structures, no matter how large the size of the printed structure is, this printing method requires the glue pool to be filled, which greatly increases the processing cost and causes material waste for using more expensive 3D printing materials. Utility Model Content

[0004] In order to solve the technical problems of the current light-curing 3D printing glue pool causing the printed object to fall off and the serious waste of printing process materials during use, the utility model provides a sunken light-curing 3D printing flexible glue pool, which can realize top-down light-curing 3D printing. The printing stage moves from top to bottom in the glue pool during the 3D printing process. During the printing process, the capacity of the flexible glue pool changes dynamically with the printing process. The structure to be printed is accumulated layer by layer on the upper surface of the printing stage to achieve layer-by-layer printing. The printed object is attached to the upper surface of the stage, which solves the problem of inverted printing being affected by gravity and causing the printed object to fall off. At the same time, the use of the flexible glue pool does not require the colloid to fill the entire glue pool, but the colloid injection amount is gradually increased through the elastic deformation of the glue pool, which saves printing materials and reduces printing costs.

[0005] The utility model is realized by the following technical solutions:

The end of the rod 3 is connected to the 3D printing stage 2 arranged on the upper surface of the lower pressure plate 5 of the flexible main glue pool, and the lifting and lowering of the 3D printing stage 2 during the printing process is realized by the stage lifting rod 3; the bottom of the flexible main glue pool 1 is connected to the glue storage bottle 8 through the silicone tube 6 and the peristaltic pump 7, and the glue storage bottle 8 stores 3D printing glue 9. The peristaltic pump 7 is used to import or export the 3D printing glue 9 in the glue storage bottle 8 into or out of the flexible main glue pool 1 to ensure that during the printing process, when the flexible main glue pool 1 is stretched or compressed, the glue liquid level is always located on the loading surface of the 3D printing stage 2, thereby realizing 3D printing layer-by-layer exposure.

[0007] Furthermore, the upper end of the flexible main glue tank 1 is connected to the flexible main glue tank upper pressing plate 4 through threads.

[0008] Furthermore, the 3D printing stage 2 is connected to the flexible main glue tank lower pressing plate 5 via threads.

[0009] Furthermore, the lower surface of the flexible main glue tank lower pressure plate 5 is provided with two through holes, one of which is used to pass through the stage lifting rod 3, and the other is used to connect with the silicone tube 6 to import or export the 3D printing glue 9.

[0010] Furthermore, the silicone tube 6 and the peristaltic pump 7 are installed in a press-type manner, and the peristaltic pump 7 squeezes the silicone tube 6 to achieve the flow of liquid in the tube.

[0011] Furthermore, the silicone tube 6 is connected to the lower pressure plate 5 of the flexible main glue tank and the glue storage bottle 8 by an inner plug to prevent leakage of the glue liquid.

[0021] Example 1

[0022] like Figure 1 As shown, the present embodiment provides a sunken light-curing 3D printing flexible glue pool, including a flexible main glue pool 1, a 3D printing stage 2, a stage lifting rod 3, a flexible main glue pool upper pressure plate 4, a flexible main glue pool lower pressure plate 5, a glue storage bottle 8, 3D printing glue 9 and a glue pool bracket 10; a circle of flexible main glue pool upper pressure plate 4 is fixed on the upper edge of the glue pool bracket 10, the flexible main glue pool 1 is located inside the glue pool bracket 10, and both sides of the flexible main glue pool 1 are made of flexible materials, which can be stretched or compressed as the amount of the internal 3D printing glue 9 changes; the upper end of the flexible main glue pool 1 is fixedly connected to the flexible main glue pool upper pressure plate 4, and the flexible main glue pool lower pressure plate 4 arranged at the lower end of the flexible main glue pool 1 is fixedly connected to the flexible main glue pool upper pressure plate 4. The lower surface of the plate 5 is perforated and a stage lifting rod 3 is installed. The end of the stage lifting rod 3 is connected to the 3D printing stage 2 arranged on the upper surface of the lower pressure plate 5 of the flexible main glue pool. The lifting and lowering of the 3D printing stage 2 during the printing process is realized by the stage lifting rod 3; the bottom of the flexible main glue pool 1 is connected to the glue storage bottle 8 through a silicone tube 6 and a peristaltic pump 7. The glue storage bottle 8 stores 3D printing glue 9. The peristaltic pump 7 is used to import or export the 3D printing glue 9 in the glue storage bottle 8 into or out of the flexible main glue pool 1 to ensure that during the printing process, when the flexible main glue pool 1 is stretched or compressed, the glue liquid level is always located on the loading surface of the 3D printing stage 2, thereby realizing 3D printing layer-by-layer exposure.

[0023] The upper end of the flexible main glue tank 1 is connected to the upper pressing plate 4 of the flexible main glue tank through threads.

[0024] The 3D printing stage 2 is connected to the lower pressing plate 5 of the flexible main glue tank through threads.

[0025] The lower surface of the flexible main glue tank lower pressure plate 5 is provided with two through holes, one of which is used to pass through the stage lifting rod 3, and the other is used to connect with the silicone tube 6 to import or export the 3D printing glue 9.

[0026] The silicone tube 6 and the peristaltic pump 7 are installed in a press-type manner, and the peristaltic pump 7 squeezes the silicone tube 6 to achieve the flow of liquid in the tube.

[0027] The silicone tube 6 is connected to the lower pressure plate 5 of the flexible main glue tank and the glue storage bottle 8 by an inner plug to prevent glue leakage.

[0028] The use process of a sinking light-curing 3D printing glue pool based on layer thickness control in this embodiment is as follows:

[0029] During the 3D printing process, the stage lifting rod 3 drives the 3D printing stage 2 to rise and fall during the printing process, thereby realizing layer-by-layer exposure of 3D printing; at the same time, since the stage lifting rod 3 and the 3D printing stage 2 move up and down, the capacity of the flexible main glue pool 1 will be stretched or compressed, thereby causing the internal glue liquid capacity to change. Therefore, when the glue liquid level in the flexible main glue pool 1 is lower than the upper surface of the printing stage 2, the peristaltic pump 7 introduces the glue liquid in the glue storage bottle 8 into the flexible main glue pool 1 through the glue tube 6, so that the liquid level rises; when the glue liquid level in the main flexible glue pool 1 is higher than the upper surface of the printing stage 2, the peristaltic pump 7 introduces the glue liquid in the main glue pool 1 into the glue storage bottle 8 through the glue tube 6, so that the liquid level drops, thereby ensuring that the glue liquid level is always located on the upper surface of the printing stage 2 during the printing process, thereby realizing layer-by-layer exposure of 3D printing.
