This research highlights the incorporation of 3D printing and blockchain technology into aeronautical manufacturing and certification procedures with an aim to increase operational efficiency. The integration of 3D printing allows for streamlined production, while the immutable features of blockchain provide traceability and certification advantages, thus offering the potential for transformative impacts within the aviation supply chain. This study primarily focuses on investigating the implications and multiple benefits of this integration into the aviation industry. Furthermore, given the absence of economic assessments priorly conducted on this integration, the study also includes a mathematical formulation that provides a quantifiable measure of the achievable return on investment. Two distinct case studies provide real data as evidence supporting the efficacy of this proposed integrated model. The outcome suggests a new paradigm for the supply chain ecosystem, leading to operational improvements and economic benefits.
