Abstract

The invention discloses a plane projection system with an auxiliary focusing function and a DLP-3D photocuring printing system based on the plane projection system.The plane projection system comprises a plane projection imaging system, a uniform illumination system, an auxiliary focusing system and a main light source, and the plane projection imaging system is arranged above a projection working face; the uniform illumination system is used for transmitting a light beam emitted by a main light source to the surface projection imaging system, and the auxiliary focusing system is used for adjusting a focusing mechanism of the surface projection imaging system, so that the surface projection imaging system projects a clear pattern on the projection working surface. According to the invention, clearer focusing can be obtained through fine adjustment of the auxiliary focusing system, and variable focusing precision in the printing process can be realized, so that the printing precision and the automation performance are improved.

Description

technical field [0001] The present invention relates to a 3D printing system, in particular to a surface projection system with an auxiliary focusing function and a DLP-3D photocuring printing system based on the surface projection system. Background technique [0002] In the existing technology, UV curing or laser sintering is shifting from traditional stereolithography (SLA) and selective laser powder sintering (SLS) to DLP (Digital Light Processor) 3D printing technology, thus forming a surface-projection UV curing and surface projection laser sintering printing technology. Among them, DLP-3D printing has the characteristics of fast printing speed and high printing accuracy. It can even realize large-format printing through splicing and rolling. Its printing speed is dozens of times faster than traditional SLA and SLS. In addition, another aspect of DLP surface projection The application is PCB maskless exposure. In the PCB etching process, there is no need to make a mas...
