The National Science Foundation awarded a $657,610 Project Grant to the University of Pittsburgh under the Engineering program (CFDA 47.041) to support research toward establishing a novel dual-wavelength photoinhibition aided photopolymer additive manufacturing process. The university will develop a digital light processing method using a second wavelength light to curb curing and enhance the geometric fidelity and functional integrity of parts. Key activities include elucidating light propagation and photochemistry reactions, establishing surrogate modeling of the new process, achieving non-contact operational characterization, and developing real-time process control via deep reinforcement learning of model predictions and in-situ measurements. The work aims to realize rapid, intelligent, precise, extensive, sustainable, and transformative photopolymer additive manufacturing. The May 1, 2023 award completion date is April 30, 2028.
