Published by Elsevier B.V. This is an open access article under the CC BY-NC-ND license (https://creativecommons.org/licenses/by-nc-nd/4.0 ) Peer-review under responsibility of the scientific committee of the ICSI 2023 organizers Abstract The structural integrity of components produced through metal additive manufacturing (AM) processes, specifically Selective Laser Melting (SLM), Laser Metal Deposition (LMD), and the fusion of these techniques, has become a paramount concern in various industries. This comprehensive review article delves into the intricate realm of structural integrity evaluation in metal AM. The review begins by providing a comprehensive overview of the significance of structural integrity in AM, emphasizing its role in ensuring the reliability and safety of components manufactured by these advanced techniques. It highlights the unique attributes of SLM, showcasing its capacity to produce complex, fully dense parts with exceptional precision, and LMD, known for its versatility in material addition and repair. Through a detailed examination of recent research and practical applications, this review article offers insights into the methods, and challenges associated with assessing the structural integrity of AM components. It addresses factors such as material properties, microstructural considerations, defects, and post-processing techniques that influence structural integrity. Furthermore, this review explores the emerging field of combined SLM and LMD processes, shedding light on their potential to enhance structural integrity by leveraging the strengths of each technique. As structural integrity remains a pivotal aspect of metal AM, this review article serves as a valuable resource for researchers, engineers, and industry practitioners seeking in-depth insights into the evaluation and enhancement of structural integrity in the context of Selective Laser Melting, Laser Metal Deposition, and their combined applications. © 2023 The Authors.
