A techno-economic analytical approach of laser-based additive manufacturing processes for aerospace application

摘要

Additive manufacturing (AM) of laser-based technological solution is developing at an exponential rate and is stepping towards industrialisation. The value and possibilities it bring to modern design and manufacturing tasks specifically for metallic products cannot be undermined. Amongst its significant benefits are; manufacturability, materials, part quality, production and economics. In spite of the benefits, uncertainties within the processes and high investment costs deter firms from implementing and adopting this technology. As such, getting to know about the technical and economic analysis model is necessary for sustainability and competitiveness of manufacturers. Consequently, while many papers in the literature provide cost estimation models for additively manufactured parts, there does not exist a thorough indicator towards decision making. Hence, a concurrent decision tool using techno-economic analysis that helps justify the implementation of laser additive manufacturing systems, and realisation performance efficiencies is explored in this study.
