Abstract
A method and system for microscale 3D printing achieve high-fidelity fabrication through the control of the light exposure time. A single pulse of light is used to initiate polymerization of a pre-polymer solution to minimize scattering-induced resolution deterioration. The printed object is fabricated in a layer-by-layer construction where each layer is formed through exposure to a single light pulse.
