Abstract

The invention discloses a high-speed resin-coated 3D printing system, including an exposure optical system, a film, a laser displacement meter, a hob, a bubble scraper, a resin tank, and a sample table; In the tank, the film covers the resin in the resin tank; the resin tank is installed on the three-dimensional motion control axis; the exposure optical system is located above the resin tank, the projection lens of the exposure optical system faces the film, and the projection lens is covered with an electromagnetic coil; the projection lens There is a laser displacement gauge on one side; there is also a hob on the top of the film, and a bubble scraper on the bottom. The invention not only provides high-speed, large-format processing capabilities, but also introduces a magnetic field to control the magnetization direction of the magnetic resin during the printing process, which improves the current resin-based 3D printing speed and allows the use of high-viscosity or high-content solid-liquid mixtures resin.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a high-speed resin-coated 3D printing system. Background technique [0002] Stereolithography (printing) first appeared as a rapid prototyping technology. Rapid prototyping technology or 3D printing technology refers to a series of technologies that directly generate full-scale prototypes from computer models, which are much faster than traditional mechanical cutting processes. Since Chuck Hull invented stereolithography in 1986, it has played its role economically and quickly in many fields, such as the visualization of complex parts, the error detection of initial design, the verification of the design function of important initial parts, and the verification of theoretical design. In the past few decades, with the investment in micro-electromechanical systems (MEMS), micro-scale stereolithography has emerged, which inherits the basic principles of traditional ...
