Researchers 3D print photo-responsive components for dynamic light modulation
Researchers in Poland and Italy have developed photo-responsive materials for vat photopolymerization that allow 3D printed components to dynamically alter the intensity and polarization of a laser beam. The materials incorporate azobenzene-based molecules whose orientation changes when exposed to polarized visible light. This creates a temporary difference in refractive index, known as photoinduced birefringence. The…
