The glass 730 is used for abutting against the transparent plate 231 and transmitting light, and the liquid photosensitive resin can be formed between the release film 710 and the forming platform 800 in a layer-by-layer photocuring mode.

After the light curing molding of the liquid photosensitive resin between the release film 710 and the molding platform 800 is completed, the molding platform 800 is driven to move upward, and at this time, the mold formed by light curing needs to be separated from the surface of the release film 710. In the process, the release film 710 needs to deform to realize separation from the model, however, since the side of the release film 710 departing from the molding platform 800 is also provided with the silicone 720, when the release film 710 deforms, the silicone 720 bonded to the release film 710 can apply a tension force to the release film 710 in a direction opposite to the deformation direction, so as to reduce the deformation tension force applied to the release film 710, so that the deformation amount of the release film 710 is smaller, the release film 710 is not easy to relax and arch, and the printing precision is higher; meanwhile, the release film 710 is not easy to damage, and the service life is longer.

Referring to fig. 1 and 12, fig. 12 shows a schematic diagram of a forming platform 800 of the 3D printing system shown in fig. 1. The forming platform 800 of the 3D printing system provided in an embodiment of the present invention is further provided with a plurality of liquid discharge holes 810, and since the plurality of liquid discharge holes 810 are provided, when the forming platform 800 moves closer to or away from the release film 710, air can flow through the liquid discharge holes 810, thereby reducing air resistance; meanwhile, when the surface of the forming platform 800 close to one side of the release film 710 is bonded with more liquid photosensitive resin, the liquid photosensitive resin can be discharged through the liquid discharge hole 810 in time, so that the resistance of the forming platform 800 in the moving process is further reduced, the phenomenon that the motor loses steps due to the fact that the forming platform 800 is subjected to large moving resistance is avoided, and the success rate of printing the model is facilitated.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent several embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
