Additive manufacturing is swiftly adopted in various industries due to its ability to boost production efficiency and reduce material waste; nevertheless, further research is still necessary to determine its sustainability, especially regarding environmental, economic, and material recycling factors. This research offers a well-rounded analysis of how Wire Arc Additive Manufacturing (WAAM) might help repair operations achieve the Sustainable Development Goals (SDGs). This study compares the energy usage of blade repair operations through Wire Arc Additive Manufacturing (WAAM) for different defects (based on their sizes) to the energy required for producing a new blade (Inconel 625), factoring in the benefits of material recycling.
