Summary
This Engineering Research Initiation (ERI) award will strengthen metal additive manufacturing by reducing defect-driven scrap and rework in laser powder bed fusion, a process used to produce geometrically complex metal parts for aerospace, biomedical, and energy systems. A common reason of build failure is the formation of streaks when the powder spreading recoater damages or disturbs. These streaks can trigger porosity and incomplete melting that propagate to later layers, degrading reliability and increasing cost, energy use, and material waste. This project will create a practical, in-proce
