Large-Scale, Two-Photon, Three-Dimensional Printing Enabled by Metaoptics

Executive Summary

We will utilize machine-learning-designed metaoptic arrays to scale up two-photon, three-dimensional printing for wafer-scale additive manufacturing, offering submicron resolution and substantially faster printing throughput. If successful, project outcomes will open doors to a vast, unexplored application space of micro/nano-architected materials, which can be rationally designed, computationally optimized, and additively manufactured for enhanced and novel functionalities in high-strain-rate mechanics, high-energy-density physics, energy storage, carbon reduction, and microelectronics.
