Abstract:

By in-situ measuring the scattered light during microstructure formation, the polymerization kinetics of three-dimensional direct laser writing are investigated in detail. Oxygen quenching, oxygen diffusion, and inhibitor depletion are shown to have substantial impact on the kinetic behavior. For typical photoresists based on multifunctional acrylates, the polymerization occurs in less than a millisecond.
