[0002] 3D printers, also known as three-dimensional printers, are based on digital model files and use special wax materials, powdered metals or plastics and other adhesive materials to print layers of adhesive materials to create three-dimensional objects. Photocuring refers to the curing process of monomers, oligomers or polymer matrices under light induction, which is generally used in the film-forming process. Photocuring technology is also used in 3D printers to form photocuring 3D printers.

[0003] In a light-curing 3D printer, a pressure plate device is required at the workbench position for supporting the printed product to connect and support the printed model during work. The pressure plate of the light-curing 3D printer in the prior art is a horizontal plate. During printing, the plate needs to be completely immersed in the liquid storage tank. Therefore, liquid will remain on the top of the plate when it is taken out, causing liquid waste. In addition, during installation, the plate is directly connected through external bolts, which are easily lost due to the separate storage of the external bolts, affecting the installation and use effect.
