Lecture
This lecture covers the principles and techniques behind achieving high resolution in 3D printing, focusing on two-photon polymerization and holographic printing. It explains the setup of conventional two-photon systems and introduces a novel approach using a digital micromirror device for high-speed and high-resolution printing. The lecture discusses the advantages, limitations, and applications of high-resolution 3D printing, including the fabrication of complex photonic and mechanical structures. It also explores the concept of multi-focus fabrication and the potential for high-throughput two-photon printing. Experimental results and comparisons with past demonstrations are presented, highlighting the submicrometer resolution and fast printing speeds achieved. The lecture concludes with simulation results and invites questions from the audience.
