Abstract
Metal Additive Manufacturing (AM) has generated a breakthrough in component manufacturing and repair processes. One of the most prominent processes is Direct Energy Deposition (DED), applying between other products for aeronautical, automotive, medical, and oil pipeline industries. The process has shown versatility and efficiency. DED operations require a correct set of process parameters involving a considerable parametrization process according to the work that needs to be done, the machine, and the material employed. Nonetheless, a lack of information about the possible uses of the different geometry beads generated by a commercial DED technology. Therefore, the dimensional characteristics of different deposited beads associated with mass flow variation values were analyzed in the present work. The experimental procedure was conducted keeping fixed parameters such as laser power, travel speed, and standoff. Some industrial applications were proposed, and significant improvements were identified for specific process parameter results.
