“…The variation in scan strategy, as well as any variation in laser spot size or build preheating, is at least partially responsible for the lack of clear trends. Werner et al [155] have compared the fatigue properties (high and low cycle fatigue) between the additively manufactured AISI 316L (L-PBF) and the wrought steel both subjected to heat treatment, showing higher fatigue limit and better finite life performance of AM AISI 316L. Likewise, Ponticelli et al [156] have investigated the L-PBF AISI 316L specimens with a quasi-static tensile test, proving that L-PBF specimens have lower elastic modulus but higher ultimate tensile strength than the original bulk material, whereby the results evidence a strong anisotropy related to the building orientation.…”

Additive manufacturing (AM) represents the present and the future of manufacturing production, thanks to a new design paradigm that allows the customization of components based on the needs of the final application, all framed in a perspective of sustainable and on-demand production. It has become an increasingly popular method for manufacturing complex and custom parts, especially those made from metallic materials, such as AISI 316L. AISI 316L is a type of austenitic steel widely used in industries such as aerospace, medical, automotive, and marine due to its excellent corrosion resistance and high strength. Thanks to its physico-chemical properties, AISI 316L stainless steel is one of the most used metals for AM. In this paper, a critical review of printing technologies, microstructural defects, mechanical properties, as well as industrial applications of AISI 316L are presented based on the state of the art. Furthermore, the main challenges with AM AISI 316L techniques are discussed, such as the influence of printing parameters, surface quality, and other common problems identified in the literature. Overall, this paper provides a comprehensive overview of AISI 316L AM techniques, challenges, and future research directions.

“…Finally, it should be noted that fatigue data shown in Figure 6 for conventional 316L cumulative refers to different studies [2,42,46,51,93]. Notably, only in a few works [46,51,64] was the conventional material was tested under the same conditions as AM 316L under investigation. More frequently, the comparison is indirect, assuming as a reference literature data, especially those reported in [2] for wrought material.…”

316L stainless steel is the material of choice for several critical applications in which a combination of mechanical strength and resistance to corrosion is required, as in the biomedical field. Additive Manufacturing (AM) technologies can pave the way to new design solutions, but microstructure, defect types, and surface characteristics are substantially different in comparison to traditional processing routes, making the assessment of the long-term durability of AM materials and components a crucial aspect. In this paper a thorough review is presented of the relatively large body of recent literature devoted to investigations on fatigue of AM 316L, focusing on the comparison between different AM technologies and conventional processes and on the influence of processing and post-processing aspects in terms of fatigue strength and lifetime. Overall fatigue data are quite scattered, but the dependency of fatigue performances on surface finish, building orientation, and type of heat treatment can be clearly appreciated, as well as the influence of different printing processes. A critical discussion on the different testing approaches presented in the literature is also provided, highlighting the need for shared experimental test protocols and data presentation in order to better understand the complex correlations between fatigue behavior and processing parameters.

“…It can be seen from these studies that the laser powder bed fusion material had a higher fatigue limit and a better finite life performance compared to wrought material and both the low and high cycle fatigue testing revealed an extensive cyclic softening. Due to rapid, repeated heating and cooling during production, a high dislocation density was present in the AM material, which was partially decreased by subsequent heat-treatments [8]. The AM applications for operating nuclear reactors started in auxiliary plant components and have slowly migrated to metallic reactor and core components, but many of these are not safety critical components.…”

This review paper provides insights the into current developments in additive manufacturing (AM) techniques. The comprehensive presentations about AM methods, material properties (i.e., irradiation damage, as-built defects, residual stresses and fatigue fracture), experiments, numerical simulations and standards are discussed as well as their advantages and shortages for the application in the field of nuclear reactor. Meanwhile, some recommendations that need to be focused on are presented to advance the development and application of AM techniques in nuclear reactors. The knowledge included in this paper can serve as a baseline to tailor the limitations, utilize the superiorities and promote the wide feasibilities of the AM techniques for wide application in the field of nuclear reactors.
