Additive manufacturing of metallic alloys is a disruptive technology that can produce net-shape components with nearly unlimited geometrical complexity and on-demand customization. This technology also brings an unprecedented opportunity to design new and modified alloys based on robust understanding of materials science. Important challenges lie ahead to desensitize dependent process variables, take advantage of thermo-kinetic process environments, and recycle feedstock for sustainable manufacturing ecosystem. In this presentation, experimental research efforts using gas atomization and laser powder bed fusion for metallic alloy development will be introduced. Progress towards fundamental understanding of microstructural development in Al-, Mg-, Ti-, Ni-, and Fe-base alloys will be documented for both commercially available and new/modified compositions. Effects of using recycled powders will be highlighted with due consideration for characteristic alloy compositions. Manufacturing ecosystem based on additive technologies is deliberated for sustainable future, wherein knowledge of thermodynamics and kinetics will play an important role.
