Parallel Nanoscale 3D Printing with Nonlinear Initiation Depletion
We report parallel 3D nanoprinting based on a one-photon nonlinear photopolymerization process by controlling the depletion and diffusion processes. We demonstrated 120nm resolution by using a compact low-cost diode laser of milliwatt power at a scanning speed of 100s-1000s µm/s. We constructed a multiphysics model to understand the process.
About Liang Pan
Professor Liang Pan currently works as an Associate Professor in the School of Mechanical Engineering and Birch Nanotechnology Center at Purdue University. He earned his M.S. and Ph.D. in Mechanical Engineering from University of California at Berkeley in 2009 and 2010, and B.S. and M.E. in Mechanics and Mechanical Engineering from University of Science and Technology of China. Prior joining Purdue, he worked as a Postdoctoral Researcher in the NSF’s Nano-scale Science and Engineering Center (NSEC) for Scalable and Integrated Nanomanufacturing (SINAM). Prof. Pan studies nanoscale light-matter interactions with an emphasis on developing novel micro- and nano-manufacturing processes, products and systems for lithography, data storage, communication, and thermal and energy applications.
