dc.description.abstractgeneralAdditive Friction Stir Deposition (AFSD) is an advanced manufacturing process that creates or repairs parts without melting the material. This research focuses on developing a small-scale version of AFSD, including new machine designs and tools for handling miniaturized materials. The study demonstrates successful deposition of high-strength alloys, like marten-sitic steel and aluminum, addressing challenges such as material buckling, heating, and tool stability. Key achievements include optimizing process parameters for multi-track and multi-layer printing, enabling printing under extreme conditions like underwater, and creating a new tool design for high-strength aluminum alloy 7050, achieving strong, high-quality deposits. This research also led to the development of a next-generation AFSD system, solving issues re-lated to material processing and modular integration. The successful implementation of this system lays the foundation for future advancements in small-scale metal additive manufactur-ing and on-site repair technologies, offering potential applications in industries like aerospace and marine engineering.en
