This book explores the evolving landscape of metal additive manufacturing (AM), with a strong emphasis on alloy development, microstructure evolution, surface engineering, and process modeling. Designed for researchers, engineers, and graduate students, it provides a comprehensive understanding of how different metallic alloys behave under various AM processes, such as selective laser melting, directed energy deposition, and wire arc additive manufacturing. It offers detailed insights into the influence of processing parameters and post-processing treatments on the mechanical and functional performance of printed parts.

• Includes both fundamental process descriptions and advanced topics such as thermodynamic modeling, real-time monitoring systems, lattice structure design, and predictive simulations.

• Gives special attention to surface modification techniques—ranging from mechanical, chemical, and electrochemical treatments to advanced coating methods—that are essential for improving fatigue life, corrosion resistance, and biocompatibility in AM-fabricated parts.

• Relevant to applications in aerospace, biomedical implants, automotive components, and energy systems.

• Bridges the gap between laboratory research and industrial application by presenting a balanced mix of theoretical foundations, practical methodologies, and application-driven case studies.

With contributions from international experts in academia and industry, this text serves as a globally relevant resource that equips readers in materials, mechanical, and related engineering fields with the tools and knowledge needed to drive innovation and solve real-world challenges in metal AM.
