Abstract

The invention discloses a multi-material photocuring 3D printing device and method, belonging to the technical field of 3D micro-nano processing. Including precision rotary platform, platform bracket, z-axis screw slide table, printing platform, release film, trough, xy connecting plate, bottom plate, y-axis screw slide table, motor frame, optical machine, shell end cover, slide Groove plate, trough clamp, xy connection block, slide table, x-axis screw slide table, belt and stepper motor. This technical solution adopts optical machine image scaling, which can better realize high-precision or large-area surface forming printing; realize multi-material printing, and can realize processing and printing of up to 4 different materials, so as to meet the mechanical properties of parts and color different needs. It has a mechanism that can clean the residual material every time the material is changed, so as to prevent contamination between different materials.

Description

technical field [0001] The invention belongs to the technical field of 3D micro-nano processing, and specifically relates to a novel light-curing 3D rapid printing device and method. Background technique [0002] With the rapid development of 3D printing and micro-nano technology, in order to meet the needs of different fields and industries, researchers at home and abroad have developed various types of micro-nano-scale 3D printing processes and printing materials in recent years, and applied them in various fields and industries. . 3D printing is rapid prototyping, RP technology is an additive manufacturing technology based on the idea of ​​discrete accumulation, a "bottom-up" material additive manufacturing method. It uses computer technology to process materials one by one according to the three-dimensional digital model of the part. Layers are connected and accumulated to produce solid parts. The manufacturing process is reduced from complex three-dimensional processin...
