Development of in-situ radiometric inspection methods for quality assurance in laser powder bed fusion
… Additive Manufacturing (AM) fabricates 3D metal parts layer-by-layer. The process enables production of geometrically complex parts that are difficult to inspect with traditional methods. The LPBF parts experience significant geometry driven thermal variations during manufacturing. This creates …

Laser Powder Bed Fusion (LPBF) of a Complex Aerospace Component: Effects of Layerwise Process Control on Part Quality
… processing parameters for a complex LPBF part. Currently, LPBF process qualification relies on empirical parameter experiments and rigorous materials characterization. Once applied to end-use, complex geometries, this process can take over 2 years of engineering effort and more than $4 …

Computational-Experimental Process Development for Laser Powder Bed Fusion Additive Manufacturing
… widespread adoption is still held back, in part due to challenges with powder handling, identification of process parameters, part qualification and quality control, and low build rates that lead to high part costs. This thesis presents workflows, tools, and understanding for practitioners …
