The impact of Additive Manufacturing (AM) on supply chain dynamics is a subject of significant relevance. AM’s ability to consolidate various components into single 3D printed models streamlines assembly processes and minimizes synchronization challenges, contrasting with traditional manufacturing methods. Digitalizing manufacturing with AM also leads to flexibility in managing inventory levels in warehouses compared to subtractive manufacturing. This article discusses the use of Additive Manufacturing for supply chain transformation in the context of the aviation industry. The article also examines two supply chain scenarios, centralized and decentralized, in the context of AM. The simulation clearly demonstrates that integrating additive manufacturing into the supply chain leads to significant improvements. The aerospace industry relies heavily on Original Equipment Manufacturers (OEMs) to develop, produce, and provide high-quality systems and components for airplanes and spacecraft. Their knowledge guarantees the assimilation of cutting-edge technology and upholds industry norms for dependability, performance, and safety. The reduction in the number of OEMs and manufacturing processes simplifies operations, while increased efficiency, cost-effectiveness, and adaptability highlight the strategic benefits of adopting an AM technology. Further detailed analysis and ongoing monitoring are recommended to optimize these benefits and address any emerging issues. The results of the study present a transformation that can increase supply chain efficiency, reduce costs, and improve adaptability. Further investigation, simulation, and analysis are needed to fully understand the effects and implications of integrating additive manufacturing into the supply chain.
