Abstract

The invention discloses a light-cured resin liquid level control device and method, which are used for measuring and controlling the air pressure of working gas in real time by utilizing a communicating vessel principle so as to make up the change of the volume of a liquid material in a light curing process and keep the working liquid level constant. The technical scheme is simple and convenient,the structure is simple, a filling block and a scraper device are not used, and rapid material supplementing and rapid planarization of the printing liquid level can be effectively achieved; and in the adjusting process, the adverse effect of large-amplitude action of the mechanism or violent flowing of liquid on the stability of the liquid level is restrained, the liquid level control precision is high, and the liquid level stabilizing time is short.

Description

technical field [0001] The invention belongs to the technical field of electromechanical and hydraulic control, and in particular relates to a light-curing resin liquid level control device and method. Background technique [0002] In order to improve the printing speed of resin photocuring 3D printing technology, such as figure 1 As shown, imaging components such as DLP projectors, laser scanning imaging machines and other optical-mechanical equipment 1 are usually used to project the image to be processed onto the upper liquid surface 3 of the liquid tank 2 formed by gravity, and realize single-layer solidification on the working platform 4 , and through the step-by-step descent of the elevator 5, in conjunction with the layer-by-layer projection of the imaging element, the layer-by-layer superposition and forming of the three-dimensional object is realized. Such a technical solution can not only improve the working efficiency of 3D printing, but also avoid the problem of...
