This book offers a unique guide to the three-dimensional (3D) printing of metals. It covers various aspects of additive, subtractive, and joining processes used to form three-dimensional parts with applications ranging from prototyping to production. Examining a variety of manufacturing technologies and their ability to produce both prototypes and functional production-quality parts, the individual chapters address metal components and discuss some of the important research challenges associated with the use of these technologies. As well as exploring the latest technologies currently under development, the book features unique sections on electron beam melting technology, material lifting, and the importance this science has in the engineering context. Presenting unique real-life case studies from industry, this book is also the first to offer the perspective of engineers who work in the field of aerospace and transportation systems, and who design components and manufacturing networks. Written by the leading experts in this field at universities and in industry, it provides a comprehensive textbook for students and an invaluable guide for practitioners This book offers a unique guide to the three-dimensional (3D) printing of metals.

Written by the leading experts in this field at universities and in industry, it provides a comprehensive textbook for students and an invaluable guide for practitioners Dr. Yang received his Ph.D. in industrial engineering from North Carolina State University in 2011, and M.S. in mechanical engineering from Tsinghua University in 2007. He is currently the assistant professor in Department of Industrial Engineering at University of Louisville, Louisville, KY, USA, with primary research focused on design of additive manufacturing and lightweight structure designs. Between 2012 and 2013, he worked as testing engineer in B/E Aerospace, and took primary responsibilities of the establishment and daily operation of the life cycle testing group. He is the recipient of 2016 International Outstanding Young Researcher in Freeform and Additive Manufacturing (FAME Junior) Award, the 2012 Emerald Engineering Outstanding Doctoral Research Award in Additive Manufacturing, and 2007 3rd Grade Scholarship of Excellency in Tsinghua University. Dr. Yang is a member of IIE, SME, SAMPE, ACerS, and TMS. He is also a member of Alpha Pi Mu (Industrial Engineering). Dr. Hsu received his Ph.D in Mechanical Science and Engineering from the University of Illinois at Urbana-Champaign in 2009. Since then he has devoted his professional life to research, teaching, and engineering consulting. More than 30 peer-reviewed journal publications has resulted from his research work which revolves around advanced manufacturing at multiple scales in both top-down and bottom-up approaches. He has 8 years of directing additive manufacturing research laboratories including the Ford Rapid Prototyping Lab at the University of Illinois, and the Advanced Multi-scale Manufacturing Lab within the Manufacturing Research and Innovation Hub at ASU. He is a member of SME. Dr. Nanu Menon received his Ph.D. in Materials Engineering from Vanderbilt University. This was followed by a post-doc appointment at USC before proceeding to work at WPAFB, Dayton, OH as a National Research Council Fellow. Since then, he has worked at Westinghouse Hanford, Richland, WA. and GE Aircraft Engines at Evendale before coming to work at Garrett in Phoenix in 1981. At Garrett/Allied Signal/Honeywell, he has been working in the Life Methods Group for the past 32 years, characterizing alloys, creating mechanical property, fatigue and creep rate models, developing life prediction codes, and establishing fractographic knowledge useful in failure analysis. Dr. Soeren Wiener is the Director of Technology and Advanced Operations at Honeywell Aerospace, where he oversees the development and deployment of game-changing manufacturing technologies into the global supply chain. Dr. Wiener earned a Master’s Degree in Mechanical Engineering from the Te
