Additive Manufacturing (AM)
The process of building parts layer by layer directly from digital models (3D printing). Unlike traditional subtractive methods, AM enables complex geometries, reduced waste, and on-demand production in metals, polymers, and composites.

Arc-Directed Energy Deposition (Arc-DED)
A wire-fed metal AM process that uses an electric arc as the heat source. It deposits large volumes of material quickly, making it ideal for structural parts. Our research focuses on MIG welding-based deposition, robotic manipulation, and controlling microstructure during deposition to make high-performance alloys viable in this high-rate process.

Large-Format Polymer Printing
Uses thermoplastic extrusion to produce lightweight, structural parts at meter scale. Our work explores toolpath design, thermal behavior, and structural performance to extend its use in aerospace, tooling, and rapid prototyping applications.
