In order for additive manufacturing to be widely accepted, the influence of both direct and indirect variables on processes needs to be understood. For this study, Selective Laser Melting process using Type 304L stainless steel is being characterized to understand the variables of build location, nearest neighbor, and build group on mechanical properties. Samples were built in near net shape and were tested in the as-fabricated condition. Samples from three different builds were used to determine the fatigue, tensile, torsion, Charpy impact and fracture toughness properties. These results indicate that the properties are influenced by many variables that may be considered secondary or higher order. They further indicate that SLM can be used for select components; however, understanding the process variables and their influence on properties is still an evolving field. This study and other like it are needed for additive manufacturing to be considered for high value added components.
