Problems solved by technology

This will cause wrinkling and deformation of the semi-permeable film covering the bottom of the photosensitive resin pool or the LCD display unit, which will reduce the accuracy of photocuring. or DLP type 3D printer) sticking occurs, and eventually the resin pool is damaged
[0004] Therefore, the photocuring 3D printers currently used have printing intervals when each layer of photosensitive resin is cured, so that the heat can be dissipated to avoid the above problems, which greatly affects the production efficiency of the 3D printer.

Embodiment 1

[0040] refer to figure 1, the present embodiment provides a resin pool 1 for photocuring 3D printers, which includes a bottom wall 11, which is arranged on the bottom wall 11 and forms a peripheral wall 12 of a first chamber 15 with the bottom wall 11, the bottom wall 11 And surrounding wall 12 can be split type design, also can integrally form. A first hole 17 and a second hole 18 are defined on the bottom wall 11 . The first hole 17 and the second hole 18 are located on the left and right sides of the bottom wall 11 . A support plate 13 is also provided in the first chamber 15 . The periphery of the support plate 13 is fixedly connected with the peripheral wall 11 , and a second chamber 16 is formed between the support plate 13 and the bottom wall 11 . The second chamber 16 is located inside said first chamber 15 . The support plate 13 is a separate component, and can also be integrally formed with the surrounding wall 11 . The support plate 13 is covered with a semi-pe...

Embodiment 2

[0044] refer to image 3 , this embodiment provides another resin pool 1' for a light-curing 3D printer, which is similar in structure to the resin pool 1 in Embodiment 1, except that the support plate 13 is replaced by an LCD display unit 13'. Therefore, this resin pool is especially suitable for 3D printers based on LCD light curing 3D printer technology. In addition, a cooling plate 19 is also provided on the lower part of the bottom wall 11 . The heat dissipation plate 19 and the bottom wall 11 form a third chamber 20 . The light source 21 is arranged on the cooling plate 19 and is located in the third chamber 20, and the light beam emitted by it can directly shine on the LCD display unit 13' through the transparent bottom wall 11, and then the light is irradiated in the third chamber according to the image displayed by the LCD display unit. A liquid photosensitive resin in a chamber 15 is solidified into a corresponding shape. In order to better solve the heat dissipat...

Embodiment 3

[0048] refer to Figure 5 and Figure 6 , this embodiment provides another resin pool 1" for photocuring 3D printers, which basically adopts the structure of the resin pool provided in Embodiment 2, except that the cooling plate 19 has a fourth chamber 23, and has a third hole 24 and a fourth hole 25 communicating with the fourth chamber 23. It should be understood that the fourth chamber 23 can be the self-structure of the cooling plate 19, or it can be formed by setting other parts It is enclosed with the heat dissipation plate 19. The upper part of the heat dissipation plate 19 is equipped with a heat dissipation fan.

[0049] During use, the water inlet pipe 6 of the liquid container 4 can be connected with the second hole 18 first, the outlet pipe 5 of the liquid container 4 can be connected with the fourth hole 25, and then the first hole 17 and the third hole 24 can be communicated with the connecting pipe 7 . A pump 3 and a radiator 8 are sequentially arranged on th...

Abstract

The present application provides a resin pool for photocuring 3D printers, comprising: a bottom wall with a first hole and a second hole; a peripheral wall for placing on the bottom wall, the peripheral wall and the bottom The wall forms a first chamber; a support plate for being arranged in parallel with the bottom wall in the first chamber, the periphery of the support plate is connected with the peripheral wall and the distance between the support plate and the bottom wall A second chamber is formed in the first chamber, and both the first hole and the second hole communicate with the second chamber. The resin pool provided by the application can fully fill the entire second chamber with cooling water, and absorb the heat accumulated by the resin pool (especially the bottom wall of the resin pool) through circulation. It has a simple structure, low manufacturing cost, and good heat dissipation effect. Moreover, the purpose of cooling can be achieved without changing the external structure of the existing resin pool, which has good versatility.

Description

technical field [0001] The invention relates to the field of light-curing 3D printers, in particular to a resin pool with a cooling device and a 3D printer using the resin pool. Background technique [0002] Existing light-curing 3D printers have a resin pool for containing liquid photosensitive resin. In order to prevent the cured and formed object from sticking to the bottom of the resin pool, in the SLA or DLP type light-curing 3D printer, a semi-permeable membrane that can permeate oxygen can be covered on the inner surface of the bottom wall of the photosensitive resin pool. In the LCD-type light-curing 3D printer, the LCD display unit is arranged on the bottom wall of the photosensitive resin pool, so a semi-permeable membrane capable of passing oxygen can be covered on the upper surface of the LCD display unit. [0003] In order to increase the photocuring speed and reduce the curing time of each layer of photosensitive resin, it is usually necessary to select a ligh...
