Additive Manufacturing of advanced Ceramics can prove to be a potential breakthrough for high precision applications like nozzle for glass quenching process. This paper presents a conceptual Life Cycle Analysis (LCA) framework to assess the environmental sustainability of 3D printed ceramic nozzles, focusing on lithographic manufacturing of alumina-based ceramic components. From extensive literature research adjoining ceramic Advanced Manufacturing process, material properties, energy consumption, and end of life analysis, this study explores key indicators that drive environmental impact and design considerations. This study further estimates the impact of sustainable manufacturing on industry 4.0 and strategizes the process considering material efficiency, energy inputs, and circularity potential. The presented facts indicate that advanced manufacturing of ceramic nozzles could substantially minimize waste, improve thermal performance and ensure greater lifecycle sustainability in comparison to traditionally manufactured nozzles. This paper aims to address the gaps by defining key concepts for sustainability-driven design and assessment of AM ceramic components in thermally intensive industrial Application.
