Abstract

Several methods have recently been proposed for improving the speed of the popular two-photon polymerization process. One such method makes use of a spatiotemporal focusing technique to achieve a planar projection printing strategy. This works uses a projection two-photon polymerization process in a continuous fashion to fabricate complex 3D structures at a large print rate while maintaining smooth surface features. Fabrication of millimeter scale structures are achievable with this continuous, layer-by-layer projection two-photon lithography system.
