This National Science Foundation (NSF) Engineering Program (CFDA 47.041) Project Grant award of $659,153 supports research investigating the reuse and recycling of feedstock in the laser directed energy deposition metal additive manufacturing process. The research aims to reveal how characteristics of reused and recycled feedstock influence melting and solidification, including how tramp elements and feedstock morphology impact melt flow, oxidation, particle segregation, and microstructure. The research approach utilizes in situ and operando experimental methods, including synchronized high-speed synchrotron X-ray imaging and diffraction. This research is expected to create a framework for feedstock reuse and recycling in metal additive manufacturing, extend reuse to new material and process systems, and elongate the service life of repaired or remanufactured components. The award period is from May 1, 2025 to April 30, 2030, and is being conducted by The Ohio State University.
