Additive Manufacturing for the Aircraft Industry: A Review

Sarat Singamneni, Yifan LV, Andrew Hewitt, Rodger Chalk, Wayne Thomas and David Jordison

Considering the stringent regulations, manufacturing of aircraft parts is often quite complex and time consuming. The multi-million components, multi-tier manufacturing systems and the severe constraints surrounding the sector lead to heavy inventory investments to achieve the just-in-time supply of parts often needed to reduce the airplane ground times. Additive manufacturing evolved allowing for the direct production of complex parts based on digital data with no complex tooling or machinery, a messiah of true just in time production. Appropriate integration of additive manufacturing with the aircraft industry could resolve some of the supply chain and inventory hurdles. Significant progress is already evident in these lines, but the lack of quality assurance attributes and certification standards is hampering the progress. The state-of-the-art of the application of additive manufacturing in the aircraft industry is reviewed in this paper. The supply chain configurations of the aircraft industry, the possible roles of additive manufacturing in relaxing the pressures in the system are evaluated. The application areas, enhanced attributes, and certification standards are critically reviewed and classified. The overall growth in the application of additive manufacturing in the aircraft industry, the main hurdles, and the future possibilities are evaluated and presented systematically, clearly portraying the developments.
