Abstract:

This study presents a comparative analysis of manufacturing techniques for 316L stainless steel, focusing on Direct Energy Deposition (DED) and traditional casting methods. The research aims to evaluate the differences in microstructure, mechanical properties, and overall performance of components produced by these two distinct processes. Through a series of experiments and material characterizations, including microscopic examinations and mechanical testing, we investigate how the manufacturing techniques influence the final properties of 316L stainless steel. Our findings reveal significant variations in grain structure, porosity, and tensile strength, highlighting the advantages and limitations of each method. This comparative study provides valuable insights for industries seeking to optimize their manufacturing processes for high-performance applications, ultimately contributing to the advancement of additive manufacturing technologies and traditional casting techniques.
