The U.S. Air Force is funding a pioneering project with 8.8 million dollars that will use digital twins to revolutionize the certification of spare parts manufactured with metal 3D printing. The goal is to streamline the production of parts for decades-old aircraft, creating a comprehensive digital history of the entire manufacturing process that ensures quality and safety, replacing costly traditional destructive tests.
Total traceability of the process: from powder to certified part 🧬
The core of the project is the creation of a digital twin of the process, not just the final product. This system, developed by the University of Oklahoma and Oak Ridge, tracks and records every parameter, from the properties of the metal powder to each layer deposited by the printer, using AI and real-time monitoring. The Peregrine software from ORNL analyzes this data to detect anomalies during manufacturing. This digital history certifies the part, allowing its manufacture or repair on different machines and locations, as long as they follow the validated virtual process, thus standardizing qualification across maintenance centers.
Beyond the part: the future is certifying the process 🚀
This use case marks a paradigm shift: certification moves from the individual physical component to the validation of the digitized process. The process twin becomes the transferable and repeatable quality standard, key for the logistics of aging fleets. This approach not only accelerates the adoption of additive manufacturing in defense but establishes a model for the aerospace industry, where absolute traceability and agility in maintenance are critical.
How can digital twins guarantee the reliability and accelerate the certification of aeronautical spare parts manufactured via 3D printing?
(P.S.: My digital twin is currently in a meeting, while I'm here modeling. So technically, I'm in two places at once.)
