ECE Colloquium Series – Professor Thomas Weller
November 1 @ 3:45 pm - 5:15 pm
As part of the *Eleanore Hale Wilson Lecture Series, ECE is proud to present:
Additive Manufacturing for Faster, Cheaper, Better, Greener Printed Electronics
Professor Thomas Weller
Oregon State University
Host: Professor Rhonda Franklin
Although additive manufacturing (AM), or 3D printing techniques have been in development for several decades, it was only a few years ago that AM found use in commercial electronics. One of the first applications was in the area of smart phone antennas, relatively simple devices from the electronics perspective but still impressive geometrically as the deposition of conductive traces on doubly-curved surfaces is required. Today, multi-material ink-jetting processes are capable of producing sensors with integrated RF functionality, while other multi-material AM technologies compete on performance with the highest quality printed circuit board laminates and add in incredible flexibility for 3D implementations. Remarkably, the same printing systems that enable applications in the GHz range can also produce low cost components operating at over 1,000 GHz. This presentation will focus on direct digital manufacturing (DDM), a 3-D printing technique that combines fused deposition modeling of thermoplastics with micro-dispensing of (conducting, insulating, resistive) pastes. Recent applications of DDM for the fabrication of 3D structural microwave and mm-wave electronics will be described.
Thomas M. Weller received the B.S., M.S. and Ph.D. degrees in Electrical Engineering in 1988, 1991, and 1995, respectively, from the University of Michigan, Ann Arbor. From 1988-1990 he worked at Hughes Aircraft Company in El Segundo, CA. He joined the University of South Florida in 1995, serving as Associate Dean for Research in the USF College of Engineering from 2007-2012 and as chair of the Department of Electrical Engineering from 2012-2018. In 2018 he joined Oregon State University as Gaulke Professor and School Head in Electrical Engineering and Computer Science. He co-founded Modelithics, Inc. in 2001. His research interests are in the areas of RF/microwave applications of additive manufacturing, development and application of microwave materials, and integrated circuit and antenna design.
