| Abstract Scope |
Wire Arc Additive Manufacturing (WAAM) has garnered attention as an economical, large-scale metal additive technology, with reduced material wastage. However, the progress has been hampered by its reliance on high-cost, proprietary robotic arm systems. This study developed a cost-effective, open-source platform with flexible hardware and software features required to efficiently conduct materials research while printing various metal alloys using Metal-Inert-Gas (MIG) welding. This poster summarizes the machine design along with an investigation of the ideal processing parameters for ER70S-6. The effects of changes in process parameters on the deposit geometry, microstructure, hardness, and impact toughness were studied. Subsequent evaluations will use the optimized parameters to print thick wall ER70S-6 structures. The goal of this work is to make WAAM platforms more accessible and to enhance its implementation across various research and manufacturing sectors.
