Several studies on the material and mechanical properties of the repaired parts also proved the feasibility of the usage of AM in the plane MRO duties . Other developments include the geometrically adaptive toolpath laser processing technique for accurate repairing by Qi et al. . The air-cooling ducts of the F-18E jet were optimised and integrated into fewer units, utilising the design flexibility possible by additive manufacturing, which also led to lesser meeting occasions and less complicated set up processes . Boeing claimed discount by 50% and 67% of the entire and production time respectively. Reduction of the part count and set up times result in reduced inventory pressures and operational costs. This may also imply decreasing the logistics costs, more choices on choice of suppliers and elimination of the non-recurring tooling costs, crucial attributes to ultimately enhance the general effectivity of the availability chain.
