PAM JAM is our monthly speaker series highlighting new and exciting photopolymer additive manufacturing research. UP NEXT: Nanzhu Zhao, Nissan Improving Throughput and Production Scalability in Vat Photopolymerization (VPP) via a Low-Adhesion, Low-Friction Printing Interface for Automotive TUESDAY, October 13, 2026 | 2:00 ET Abstract: Vat photopolymerization (VPP), particularly digital light processing (DLP), provides exceptional resolution for polymer additive manufacturing but remains limited in high‑throughput industrial deployment due to slow recoating dynamics and strong resin–window adhesion. This study introduces a novel printing interface engineered to reduce interfacial adhesion while enhancing resin flow behavior, enabling rapid layer replenishment and significantly increasing build rates. The interface architecture was evaluated through controlled experiments and integrated into automotive prototyping workflows at Nissan. Results demonstrate substantial improvements in throughput, process stability, and scalability, supporting small‑ to medium‑volume production of end‑use polymer components. Case studies highlight successful fabrication of geometrically complex automotive parts, illustrating how this interface transforms VPP from a prototyping‑centric technology into a viable production method for automotive manufacturing environments. |
