Abstract
Photocuring, the light-driven process of transforming liquid resins into solid objects, has been a cornerstone of 3D printing technology. Traditionally dominated by engineering disciplines, this method has achieved unparalleled build speeds and resolution in additive manufacturing. However, the reliance on high-energy UV light has constrained material options due to degradation, light attenuation, and energy-demanding operation.
This talk introduces chemical innovations that shift the photocuring spectrum from UV to more gentle and energy-efficient visible wavelengths. This paradigm shift not only enhances material compatibility but also significantly expands the range of printable objects while reducing the photochemical burden associated with high-energy light. Our research has yielded novel panchromatic resins, enabling rapid, high-resolution 3D printing using visible light.
