Additive manufacturing has become a key technology in numerous industrial sectors, driven by the increasing use of metallic materials. Its significant advantages, such as increased design flexibility, reduced material usage, and improved customization possibilities, highlight its potential to revolutionize traditional manufacturing processes. This study presents a comparative analysis of two additive manufacturing processes, namely selective laser melting and wire laser metal deposition. Both methods allow the manufacture of complex parts and leverage the benefits of topology optimization. The study focused on 316 L stainless steel applications and analyzed both the mechanical properties and the material and energy consumption required for its production, based on experimental measurements and literature data. Differences in tensile behavior, as well as energy and material efficiency between the two processes, are analyzed. A decision matrix is ​​proposed to aid in the selection of the most appropriate manufacturing process for the case under study. The need to assess environmental impact alongside mechanical performance when selecting additive manufacturing technologies is addressed, thus contributing to the development of more sustainable manufacturing practices.
