Photocuring 3D printing device and printing method

Abstract

The invention provides a photocuring 3D printing device and a printing method. The photocuring 3D printing device comprises a liquid tank, a liquid tank lifting mechanism, a printing platform and a printing platform lifting mechanism. The printing platform is disposed in the liquid tank, a membrane immersing mechanism is arranged at the upper end of the liquid tank and comprises a membrane stretching mechanism and an immersed membrane fixed on the membrane stretching mechanism, and the printing platform is located at the lower end of the immersed membrane. By arranging the membrane immersing mechanism, resin at the upper end of the printing platform can be oppressed for leveling through the immersed membrane immersed in the resin, the waiting time of leveling of a liquid level is greatly shortened, and the forming efficiency is improved.

AI Technical Summary

Benefits of technology

This technology helps improve the speed at which liquids are applied during manufacturing processes while reducing wait times between when they start being filled with solvents or other fluids before reaching their final destination.

Problems solved by technology

This patented describes different ways how microscopic three dimensional structures may be printed on surfaces like plates used in various industries such as electronics, optics, biology, medicine, etc., but they all require some type of material called photopolymerizable resins. These materials have unique characteristics that allow them to harden quickly without leaving any residue behind from their own chemical reaction. By controllably adding more layers onto top of these resists before being fully solidified, precise levels can be achieved over longer periods of time compared to traditional techniques. Additionally, if the printer has multiple print modes - either mode requiring separate steps between two successive stages or allowing only one stage per second, then slowdown times caused by relying upon gravity to keep the remaining part still remain constant could lead to errors in printing results.
