| Abstract Scope |
In metal based additive manufacturing processes such as Laser Engineered Net Shaping (LENSŪ), the primary feedstock is gas atomized powder because of its spherical morphology and controllable particle size. Unfortunately, this method of using gas atomization consumes a significant amount of energy and cost. Research has demonstrated that machine chips and other waste metal products can be processed into powder and then utilized as alternative feedstock materials for the additive manufacturing process. In this study, gas atomized powder and these alternative powder sources are evaluated and compared on the basis of energy demand, cost, and environmental impact. Life cycle and techno-economic assessment methodologies are utilized, assuming a system boundary that includes the extraction and processing of the raw materials, as well as the LENSŪ deposition of parts. Recycling of the powder waste in the LENSŪ process is also considered. |
