Currently, the photocuring 3D printing and forming mainly includes laser Stereolithography (SLA) 3D printing and forming and Digital Light Projection (DLP) 3D printing and forming. And the matched photosensitive resin is the core technology for realizing photocuring 3D printing. Heretofore, a photocurable photosensitive resin for 3D printing is mainly a resin mainly composed of urethane acrylic, epoxy compound, vinyl ether, and the like, and most of the available commercial photosensitive resins have been developed by foreign and international companies and are expensive.
To date, 405nm SLA 3D printing technology has great advantages for the popularization and promotion of 3D printing at civilian customers. Based on the above, the research and development trend of 405nm SLA 3D printing technology is raised in the domestic 3D printing field, and a plurality of 405nm laser photocuring 3D printers have been successfully developed. In addition, many DLP type photocuring 3D printers also employ a 405nm light source.
