| Abstract Scope |
The utilization of a hot wire-laser direct energy deposition approach to create metallic components based on hybrid manufacturing has been investigated in this work. By integrating several complementary traditional processes, this hybrid manufacturing strategy combines the simultaneous advantages of additive manufacturing (complex geometries, part consolidation, and mass customization) with the advantages of subtractive manufacturing (better surface finish and enhanced dimensional accuracy). This study program has examined the basic processing-property connections of printed metals, with a focus on Invar-36 due to its performance in terms of low coefficient of thermal expansion, which is a critical feature for the creation of composite tooling. Here, the effect of the printing parameters and toolpaths on its mechanical and thermal properties has been examined. 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. |
