摘要:3D轻量化打印制造依据材料特性的分子设计和微纳尺度的几何构型，能够在能量耗散和操纵波导方面赋予材料革新性的性能。这些超材料在结构、催化、以及能源转化展示了广泛的应用。

In this seminar, I will present our development of three dimensional micro/nanofabrication technique, projection microstereolithography (PuSL), to enable design and exploration of digitally coded multifunctional and multimaterial lightweight metastructures at unprecedented dimensions. The ultra-high resolution and multi-material capabilities of the 3D printing system and the modeling tools developed can be used to design and fabricate architected materials for combined functions, including energy absorption, actuation/morphing, and micro-scale bioreactors for tissue engineering. These structures show promise on focusing and rerouting acoustic waves through broadband and highly transparent metamaterials. I will also discuss the development of engineered, three dimensional arrays of copolymer fibers that serve as mimetics of neuronal axons, using a combination of materials engineering and high resolution 3D microfabrication, which enable study of OPC engagement and subsequent myelination in vitro.

Bio sketch:Nicholas X. Fang received his BS and MS in physics from Nanjing University, and his PhD in mechanical engineering from University of California Los Angeles. He arrived at MIT in Jan 2011 as Associate Professor of Mechanical Engineering. Prior to MIT, he worked as an assistant professor at the University of Illinois Urbana-Champaign. Professor Fang’s areas of research look at nanophotonics and nanofabrication.  His recognitions include the ASME Chao and Trigger Young Manufacturing Engineer Award (2013); the ICO prize from the International Commission of Optics (2011); an invited participant of the Frontiers of Engineering Conference by National Academies in 2010; the NSF CAREER Award (2009) and MIT Technology Review Magazine’s 35 Young Innovators Award (2008).
