Metal additive manufacturing (MAM) is an exciting emergent technology that offers the possibility of democratizing metal manufacturing worldwide. Many believe it has the ability to revolutionize product manufacturing on a global scale. MAM will require a considerable design shift for manufacturers and, hence, will disrupt conventional thinking and require adaptation. Visionaries in the mobility industry can see the transformative possibilities after materials considerations are addressed./ Materials Technology Gaps in Metal Additive Manufacturing introduces the reader to various opportunities and relationships in the study of material technologies involved in metal-based additive manufacturing of aerospace and automotive parts. Everything starts and ends with the material feedstock, and the intermediate processes that affect a particular metal. Each of the choices in the complex integrated MAM system impacts final-part properties. Edited by Dr. Cynthia K. Waters, from North Carolina A&T State University, Materials Technology Gaps in Metal Additive Manufacturing is a highly curated collection of 10 seminal SAE International papers. They discuss the various technologies involved in MAM, and draw attention to the materials needs in each of the situations addressed. The main topics included in Materials Technology Gaps in Metal Additive Manufacturing are: Process design and material modeling Metal powder selection and study Additive processing parameters' effect on materials properties As more interdependencies of material properties and possible manufacturing processes evolve (compatibility interdependence), questions if the specific manufacturing process is capable to create the required geometry will also arise. Materials Technology Gaps in Metal Additive Manufacturing brings innovative ways to address these and other challenges that are always present in the adoption of novel technologies.

This book is a technical introduction to additive manufacturing (AM) with a focus on powder bed fusion and metals. It provides the theory and industry-based practices to design, make, and test metal components via AM. After outlining the methods and materials of powder bed methods, the book explains the workings and physical limitations of electron beam and laser melt technologies in manufacturing parts, using a variety of metal powders. In this context, the physics of powder melting is described, as well as the effects of temperature variables on the properties of a part. The critical elements of how powder feedstock is chosen and formulated are explained. Processing methods are described using original design and engineering parameters developed by the author. Information is provided on current test methods of metals produced by AM, as well as how to carry out quality control, monitor reliability, and implement safety standards. For process design, a section is devoted to modeling.Each chapter includes a set of problems for students and practitioners that reflect metals' fabrication in industry.

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

Extensive listing of terms, definitions, and acronyms provides the reader with a quick reference guide to the language of AM metal processing. The book directs the reader to a wealth of internet sites providing further reading and resources, such as vendors and service providers, to jump start those interested in taking the first steps to establishing AM metal capability on whatever scale. The appendix provides hands-on example exercises for those ready to engage in experiential self-directed learning.

The field of additive manufacturing has seen explosive growth in recent years due largely in part to renewed interest from the manufacturing sector. Conceptually, additive manufacturing, or industrial 3D printing, is a way to build parts without using any part-specific tooling or dies from the computer-aided design (CAD) file of the part. Today, mo
