In the current UV-curable 3D printing industry, machines used in different application areas have varying requirements for light-source spot uniformity and power. For consumer-grade printers, the typical specifications are a light-spot uniformity of at least 80% and a power output of no less than 3,500 µW/cm². Given the stringent cost-control demands for consumer products, the industry currently relies heavily on point-source plano-convex matrix collimated-light sources; however, this approach entails high manufacturing precision requirements for aluminum substrates and mounting brackets, as well as substantial tooling costs.
Based on existing photopolymerization 3D printing technology, how to develop a more advanced composite optical lens for use in 3D printers—capable of generating light spots that meet requirements for uniformity and small divergence angles, thereby improving the success rate of profile formation—has become an urgent challenge that practitioners in this field need to address.
