| Abstract Scope |
The present work has explored the use of a hot wire-laser direct energy deposition process to produce metallic parts based on a hybrid manufacturing. This hybrid approach combines the simultaneous benefits of additive manufacturing (complex geometries, part consolidation, and mass customization) with the advantages of subtractive manufacturing (superior surface finish and enhanced dimensional accuracies) by integrating a suite of complementary traditional processes. This research program has studied the fundamental processing-property relationships of printed metals, with a particular interest on Invar-36 due to its low coefficient of thermal expansion performance, which is a feature of great interest on the production of composite tooling. Here, the effect of its printing parameters and tool paths have been investigated in terms of its mechanical-thermal properties. These results have provided the basic understanding of hybrid manufacturing, which is being expanded on the production of tooling parts for the automotive and aerospace sector. |
