Traditional manufacturing techniques fade into the background, while manufacturing systems require using additive technologies for rapid adaptation to current demand and reduction of production cycle duration. Many large mechanical and aircraft engineering companies have already adopted additive manufacturing technologies in their future production strategy. The general concept of 3D printers on the basis of e-manufacturing principles is aimed at the integration of computer models of physical objects and processes. This change requires a big transformation of the enterprise business model, affecting either core or support activities. For instance, additive manufacturing could also change project management practices. This paper aims to identify how additive manifacturing could transform the project management function for the aerospace industry. Results show that projects could improve their performance by integrating additive manufacturing; however, project managers could adapt their approach to a new paradigm for lifecycle management and for leaner supply chain management in aerospace industry.
