| Abstract Scope |
Both novel alloy and functionally graded material (FGM) development present opportunities to design performance-optimized metallic components by spatially varying composition and microstructure. This aligns with emerging goals in additive manufacturing (AM) to tailor properties at voxel-scale resolution for critical aerospace, defense, and energy applications. However, the cost and scalability challenges of such work often hinder real-world implementation. To address this, we are introducing here a Directed Energy Deposition (DED) platform with multi-material deposition capabilities, incorporating in-situ monitoring, closed-loop control, and automated toolpath planning to support consistent transitions across dissimilar alloys such as Inconel, titanium, and stainless steel. This presentation will highlight recent developments in DED that enable novel alloy development, advanced gradient path planning, and strategies for data-driven process optimization. In addition, recent collaborations—including those focused on defense applications—demonstrate how modern DED technology supports the shift toward certifiable, compositionally engineered AM components with enhanced performance and reduced qualification risk. |
