Abstract

The invention discloses a light-curing three-dimensional printer based on digital light processing (DLP) projection, which comprises a computer system (2), an automatic control system, a DLP projection system (1), a molding work pool (3), a feeding system (4) and a lifting system. Compared with the three-dimensional printer in the prior art, the light-curing three-dimensional printer has the advantages of high molding speed and high printing precision, and the surface of a molded product is continuous and is not layered; moreover, the DLP projection-based light-curing three-dimensional printer can be applied to performing light curing on light-sensitive materials with various strengths and made from different raw materials.

Description

technical field [0001] The invention relates to the field of three-dimensional printing rapid prototyping, in particular to a three-dimensional printer based on DLP projection light curing. Background technique [0002] Three-dimensional printing is based on the computer three-dimensional design model, through the software layered discrete and numerical control forming system, using laser beams, hot-melt nozzles, etc. to accumulate and bond special materials such as metal powder, ceramic powder, plastic, and cell tissue layer by layer , and finally overlay molding to create a technology for physical products. This technology is an growth-oriented manufacturing technology based on the idea of ​​"discrete / stack". It uses computer technology to discretize the 3D model into a series of 2D cross-sectional views along one direction, and then prints and accumulates them layer by layer according to the information of the cross-sectional views. In each layer of printing, the precisi...
