Additive manufacturing (AM) methods have grown and evolved rapidly in recent years. AM for polymers is an exciting field and has great potential in transformative and translational research in many fields, such as biomedical, aerospace, and even electronics. Current methods for polymer AM include material extrusion, material jetting, vat polymerisation, and powder bed fusion. With the promise of more applications, detailed understanding of AM—from the processability of the feedstock to the relationship between the process–structure–properties of AM parts—has become more critical. More research work is needed in material development to widen the choice of materials for polymer additive manufacturing. Modelling and simulations of the process will allow the prediction of microstructures and mechanical properties of the fabricated parts while complementing the understanding of the physical phenomena that occurs during the AM processes. In this book, state-of-the-art reviews and current research are collated, which focus on the process–structure–properties relationships in polymer additive manufacturing.

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.

Additive manufacturing (AM) of metals and composites using laser energy, direct energy deposition, electron beam methods, and wire arc melting have recently gained importance due to their advantages in fabricating the complex structure. Today, it has become possible to reliably manufacture dense parts with certain AM processes for many materials, including steels, aluminum and titanium alloys, superalloys, metal-based composites, and ceramic matrix composites. In the near future, the AM material variety will most likely grow further, with high-performance materials such as intermetallic compounds and high entropy alloys already under investigation. Additive Manufacturing Applications for Metals and Composites is a pivotal reference source that provides vital research on advancing methods and technological developments within additive manufacturing practices. Special attention is paid to the material design of additive manufacturing of parts, the choice of feedstock materials, the metallurgical behavior and synthesis principle during the manufacturing process, and the resulted microstructures and properties, as well as the relationship between these factors. While highlighting topics such as numerical modeling, intermetallic compounds, and statistical techniques, this publication is ideally designed for students, engineers, researchers, manufacturers, technologists, academicians, practitioners, scholars, and educators.
