The U.S. Navy is drastically reducing the costs of F/A-18 tyre replacements thanks to additive manufacturing. Normally the cost is around $100,000, and thanks to 3D printing/cold spray technology they have reduced the cost to just $300 per repair. This huge cost saving comes as part of a broader effort to rethink sustainment strategies and reduce expenses across the fleet.
Replacing F/A-18 tires has traditionally been an expensive endeavor, with each assembly costing nearly six figures. However, by utilizing cold spray technology in conjunction with 3D printing, the Navy has identified a cost-effective solution. Theodore Gronda, program manager for Naval Air Systems Command’s Additive Manufacturing Team, revealed that approximately 80% of damaged tire rims are repairable using this method.
Cold spray technology involves depositing metal particles onto a surface at high speeds, effectively rebuilding worn or damaged parts. This process not only restores the structural integrity of the components but also significantly reduces maintenance costs. With each repair taking just two hours and costing $300 per wheel, the Navy stands to save millions annually compared to traditional replacement methods.
While these advancements offer substantial benefits, logistical challenges remain. Cold spray repairs currently require shore-based facilities due to environmental considerations. However, the Navy’s commitment to additive manufacturing is evident through initiatives like the Naval Aviation Schoolhouse for Additive Manufacturing, which aims to train personnel in advanced manufacturing techniques.
By embracing additive manufacturing and cold spray technology, the Navy is not only reducing costs of tire maintenance but also redefining its approach to sustainment. This shift towards repair-focused strategies promises to yield significant cost savings while enhancing fleet readiness and operational efficiency.
