Additive Manufacturing for Innovative Applications

Additive manufacturing techniques offer promising methods especially with their rapid turnaround time, potential for part consolidation, and manufacturing complex and innovative parts. It has been proven that parts with moving components, lattice structures, and maleable geometries are possible to print using AM. Potential applications include but are not limited to aerospace, energy, and defense applications.

Characterizing the Complex Process-Structure-Property Relationships in Metal Additive Manufacturing

Due to their unique manufacturing processes that require melting metal in a layer-by-layer fashion, additively manufactured (AM) metal components undergo high solidification rates and heat cycling. All of these result in variability in the underlying microstructure from one build to the next or even within the same build. With the variability of the microstructure, the resulting material properties are also expected to vary within the same build. Therefore, there is an innate need to evaluate the spatial variability of the mechanical properties and the underlying structures of AM metallic components to characterize the complex process-structure-property relationships.
