Title:
From Promise to Production: Unleashing the Potential of Additive Manufacturing
Abstract:
Additive Manufacturing (AM) provides unique opportunities to spatially control the deposition andpatterning of materials. This provides the well-known ability to crate complex geometries with low lead time. However, there are many additional challenges and opportunities that arise from this spatial control including altered economic considerations, new sources of defects, and challenges for quality assurance. Developing workable solutions demands creative engineering. In this talk, I will present examples of unique challenges and opportunities in additive manufacturing drawn from our research. I will discuss the fundamental tradeoff between exposure time and area that appears across many processes and show how this tradeoff can be utilized to expand material options in powder bed fusion. In the second phase, I will discuss the competition between properties during deposition and patterning and how the competing requirements can be bridged in binder jett AM. Finally, I will address the challenge of assuring quality in AM processes and a strategy for using non-contact thermal property measurements to obtain critical data during AM operations.
Bio:
Dr. Nathan Crane’s research expertise focuses on design and advanced manufacturing with a particular interest in additive manufacturing (AM) and digital microfluidics. Recent projects have included pulse thermography studies of AM systems, multi-material fabrication in laser powder bed fusion, and characterization of droplet/powder interactions in metal binder jet printing.
Dr. Crane is a professor of Mechanical Engineering at Brigham Young University. He was previously associate and assistant professor of Mechanical Engineering at the University of South Florida. Dr. Crane received his B.S. and M.S. degrees in Mechanical Engineering at Brigham Young University in Provo, UT and a Ph.D. at the Massachusetts Institute of Technology. He has worked in industry (Caldera Engineering and Pratt and Whitney Aircraft) government (Sandia National Laboratories, Los Alamos National Laboratories), and academia. He has over 100 peer-reviewed publications and has 12 patents. Dr. Crane is currently an Associate Editor for the top manufacturing journal, Elsevier’s Additive Manufacturing.
