Abstract Scope Stainless steel type 316L is a low-carbon chromium-nickel-molybdenum austenitic steel. Due to its remarkable corrosion resistance and excellent mechanical properties, it has been applied to many fields such as food, architecture, aircraft, and automotive industries – ranging from cryogenic to intermittent temperature applications. Ergo, 316L (SS) stands as a perfect candidate for advancing the application of metal AM techniques to the mainstream manufacturing sectors. This talk will present the unique microstructural evolution and mechanical response of 316L (SS) printed using two mainstream metal AM techniques – electron beam powder bed fusion (EB-PBF) and laser-directed energy deposition (L-DED). The effect of processing conditions, process parameters, and part geometries on the melt pool solidification parameters, grain growth and deformation mechanisms are explored through experimental investigations and computational modelling. Moreover, innovative printing strategies are discussed that provide improved control of grain growth during solidification.
