About

D. Costanzo is a leading researcher in advanced manufacturing, specializing in wire arc additive manufacturing (WAAM) and the processing of high-performance alloys. Their work focuses on understanding how process parameters—particularly current mode—influence the microstructural and mechanical properties of additively manufactured components. Costanzo’s most cited paper, "Current mode effects on weld bead geometry and heat affected zone in pulsed wire arc additive manufacturing of Ti-6-4 and Inconel 718" (2020, 88 citations), is a seminal contribution that systematically characterizes how pulsed current alters bead morphology and heat-affected zone dimensions in titanium and nickel-based superalloys. This research provides critical guidance for optimizing deposition strategies to minimize defects and improve part integrity. By bridging the gap between welding science and additive manufacturing, Costanzo’s work has direct implications for aerospace, biomedical, and energy sectors, where reliable, high-strength components are essential. Their findings are widely cited by engineers and materials scientists seeking to refine WAAM processes for industrial adoption. Costanzo’s contributions underscore the importance of process-structure-property relationships in next-generation manufacturing technologies.
