Oscillation assisted 3D printing renders ultrafast fabrication of microlens array

An oscillation assisted digital light processing (DLP) based 3D printing approach is developed to enable ultrafast fabrication of microlens arrays with optically smooth surface (1 nm surface roughness) via a single 1-3 seconds exposure of grayscale UV light.
