| Abstract Scope |
Arc based micro plasma additive manufacturing has been developed to fabricate alloy components with higher resolution, lower heat input, and greater versatility than existing wire arc direct energy deposition (DED) techniques. The low heat input, high precision arc is well suited for producing small scale metallic vital components. This study evaluates the process using 0.5 mm wire, Ni-based alloy 600 and 304 stainless steel, deposited with an anthropomorphic FANUC LR Mate 200iD7L robot equipped with a PMC plaTo100M torch. Results demonstrate the capability to 3D print high resolution walls around 2 mm thick at currents down to 20 A. In-situ highspeed video analysis quantifies metal transfer stability and the relative positions of the wire and electrode, while post build characterization links process parameters to deposit geometry and microstructure. These findings elucidate the fundamentals of micro plasma additive manufacturing relative to established techniques and define process windows for producing defect free features. |
