Fundamentals of Laser Powder Bed Fusion of Metals

Prof. Igor Yadroitsev is a Research Chair in Medical Product Development through Additive Manufacturing at the Central University of Technology launched by the National Research Foundation of South Africa in 2015. He has been involved in additive manufacturing with emphasis on laser powder bed fusion at the Vitebsk Institution of Technical Acoustics (Belarus) since 1995, when this technology was in its infancy. He continued his research in the field at the National School of Engineering (Saint-Étienne, France) and published a book on selective laser melting in 2009. His research interests include applied optics and laser technologies: additive manufacturing, laser powder bed fusion of metals and plastics, laser processing, materials science, and optics. He has authored over 100 articles in the field of laser powder bed fusion. Dr. Ina Yadroitsava, PhD, has been involved in additive manufacturing since 2007 when she started to work in the Laboratory of Diagnostics and Engineering of Industrial Processes at the National School of Engineering (Saint-Étienne, France). At present, she is working as Senior Researcher at the Department of Mechanical and Mechatronic Engineering, Faculty of Engineering, Built Environment and Information Technology at the Central University of Technology, Free State. In 2019, she was recognized by the South Africa National Research Foundation as an established researcher in such areas as laser metal additive manufacturing, advanced materials and numerical modeling. Her research interests include laser powder bed fusion, material characterization, bio-medical applications, and properties of advanced additively manufactured materials. Prof. Anton Du Plessis is Associate Professor at Stellenbosch University (South Africa) and Applications Scientist at Object Research Systems (Canada). His research spans X-ray tomography applications, additive manufacturing and engineering materials. He has published over 150 journal papers and is on the editorial board of a number of journals, and acts as deputy editor of Additive Manufacturing Letters and editor in chief of Tomography of Materials and Structures. He holds extraordinary professor positions at Nelson Mandela University and Central University of Technology (South Africa). Prof. Eric MacDonald, PhD, is a Professor of Mechanical Engineering and the Murchison Chair at the University of Texas at El Paso, as well as deputy editor of the Elsevier journal 'Additive Manufacturing'. Dr. MacDonald received his PhD degree in Electrical Engineering from the University of Texas at Austin and has worked in industry for 12 years at IBM and Motorola, and subsequently co-founded a start-up — Pleiades, Inc., which was acquired by Magma Inc. (San Jose, CA) in 2003. Dr. MacDonald has held faculty fellowships at NASA's Jet Propulsion Laboratory, SPAWAR Navy Research (San Diego), and a State Department Fulbright Fellowship in South America. His research interests include 3D-printed multi-functional applications and advanced process monitoring in additive manufacturing.

"I just finished reading the latest book entitled Fundamentals of Laser Powder Bed Fusion of Metals published by Elsevier which I found to be of exceptional quality. The topics are coherently and overarchingly discussed right from the basics of laser powder bed fusion to its physics and modelling, porosity defects, residual stresses, non-destructive characterisation, process monitoring, lattice materials, metamaterials, mechanical properties, novel material developments and future trends. Altogether there are 24 chapters, each authored by respective leaders in the field totalling 58 authors from around the globe. The book concludes with an interesting case study that puts some of the key aspects into perspective. Overall, this is the most comprehensive book regarding laser powdered bed fusion of metals to date. As such it is a recommended reading for undergraduates, postgraduates, researchers, and advanced practitioners in the field of metal additive manufacturing. The book is suitable both for guided learning and quick reference." --Dr Arun. Arjunan
