AM expands the definition of 3D printing to encompass a variety of procedures that begin with a three-dimensional computer model, incorporate an AM production procedure, and result in a useful product. The AM process can be confusing due to the rapid rise of competing techniques for fabricating 3D parts. This volume provides a thorough review of the basic components and procedures involved in additive manufacturing. It outlines a road map for where to begin, what to study, how everything goes together, and how AM might enable ideas outside traditional processing to realize those ideas in AM. Furthermore, this book investigates the benefits of AM including affordable access to 3D solid modeling software. With this software, learning is achieved without having to invest in costly industrial equipment. AM encompasses a variety of techniques, including those that use high-intensity beams to fuse powder or wire, and hybrid techniques that combine additive and subtractive manufacturing techniques. AM-related processes have developed at breakneck speed, giving rise to a deluge of acronyms and terminology, not to mention the emergence, acquisition, and demise of new businesses. By combining ideas and aspirations, better methods will be revealed that result in useful products that will serve and contribute to a lasting future. Although expensive commercial additive manufacturing equipment can cost hundreds of thousands to millions of dollars, a lack of access to equipment does not preclude the study of the technology. 3D printing services will undoubtedly become more reasonable for small- and medium-sized organizations as their prices decline. Hybrid 3D plastic printing technologies and low-cost hobbyist 3D weld deposition systems are already in development which will make the best 3D printers accessible and affordable. This book will assist the reader in determining what is required to begin, which software, supplies, and procedures best suit, and where to obtain additional information. Audience The book will be used by engineers and R&D researchers involved in advanced additive manufacturing technology, postgraduate students in various disciplines such as mechanical, manufacturing, biomedical, and industrial engineering, etc. It will also serve as a reference manual for manufacturing and materials engineers involved in additive manufacturing and product development.

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.

The advent of additive manufacturing (AM) processes applied to the fabrication of structural components creates the need for design methodologies supporting structural optimization approaches that take into account the specific characteristics of the process. While AM processes enable unprecedented geometrical design freedom, which can result in significant reductions of component weight, on the other hand they have implications in the fatigue and fracture strength due to residual stresses and microstructural features. This is linked to stress concentration effects and anisotropy that still warrant further research. This Special Issue of Applied Sciences brings together papers investigating the features of AM processes relevant to the mechanical behavior of AM structural components, particularly, but not exclusively, from the viewpoints of fatigue and fracture behavior. Although the focus of the issue is on AM problems related to fatigue and fracture, articles dealing with other manufacturing processes with related problems are also be included.
