Additive manufacturing (AM) of metals is vital due to its customizability, energy efficiency, swift availability, and lower cost as compared with conventional wrought material. The uncertainty of the efficiency of this material is in the differing microstructure compared with the wrought material. AM materials impose a new complexity through the build pattern of the particular additive process, powder, and parameters used in addition to the polycrystalline microstructure created within that pattern.
Significant microstructural differences may be obtained for changes in the deposition process, parameters used, or the shape of the deposited material.
This project is aimed at comparing microstructures of tantalum built using different power parameters and layer thicknesses using the same stock powder material and deposition method on the EOS M280. Post-mortem metallographic analysis will be used to compare each sample microstructure to unveil connections between differing microstructures obtained with the different build parameters.
