Abstract

The third biannual Photopolymer Additive Manufacturing Alliance Workshop was held on September 15-16, 2025, at the University of Colorado Boulder to continue its mission of advancing photopolymer additive manufacturing (PAM). Building on the 2023 PAMA Workshop, the 2025 iteration brought together leaders from industry, national laboratories, academia, standards organizations, and startups to assess the current state and future trajectory of PAM, also known as vat photopolymerization (VPP). The workshop centered on four panels themed around the state-of-the-field and outlook, novel materials and metrology, and safety and standards, with a final panel focusing on an innovative VPP newcomer, volumetric additive. All panels highlighted the need to integrate material and hardware innovation with AI-driven data infrastructure, standardized metrology, and regulatory readiness to accelerate an application-driven manufacturing approach.
