Abstract Scope |
Wire-laser directed energy deposition (WL-DED) is a novel technique that allows the production of large-scale metallic components with a relatively high deposition rate. The high cooling rates experienced in additive manufacturing processes create unique microstructures typically not seen in traditional manufacturing methods. Since the local cooling rates are in part a result of the processing parameters selected, it flows that changing the printing parameters as a function of position can lead to a change in microstructure and mechanical properties. In this study, Meltio M450 LW-DED printer is used to enable location-specific microstructure and properties by varying printing parameters such as scan strategy and hatch spacing during a print. The effects of changing these variables on the mechanical properties of 316L stainless steel samples printed in different orientations are studied and discussed. |
