Digital Light Processing 3D Printing of Polymer Composites Based on Tunable Curing Resins with Photoswitchable Molecules.

ABSTRACT: This study presents an additive manufacturing (AM) technique, photoswitchable direct light processing (P-DLP), which utilizes a dynamic mask imaging photoinitiation approach to mitigate light-scattering effects caused by filler particles like silicon carbide (SiC) in composite printing. Vat photopolymerization AM process offers high precision but faces significant challenges in balancing speed and resolution, material instability, and requiring extensive support structures during fabrication. The P-DLP technique overcomes these limitations by employing a dynamic masking system, where ultraviolet (UV) light initiates photopolymerization and visible (blue) light selectively inhibits undesired polymerization. This mechanism allows for precise control over the curing process, enabling the fabr
