| Abstract Scope |
Hybrid manufacturing, which combines additive and subtractive manufacturing, allows for the complexities of additive manufacturing along with the finish and accuracies of subtractive manufacturing. Hot wire-laser direct energy deposition uses a metal wire, which can either be the same alloy or a different alloy as the base metal, to build the desired shape, or repair a damaged tool. Optimizing the printing process, to include direction of the wire in each layer, and examining the process-property relationships is important, especially if this technique is to be utilized to repair damage tools for continued use. The research presented here will compare SS316L specimens printed unidirectional, with the wire only moving along one axis, and bi-directional, with the wire moving along either the x or y axes. Mechanical properties, including tension and hardness, porosity, and coefficient of thermal expansion will be determined and compared to determine how print direction affects properties. |
