The Navy thinks 3D printing can eliminate a wide range of challenges with its supply chain. The service is already testing the idea of using additive manufacturing technologies to build small spare parts aboard ships, as they’re needed, rather than having to transport them from supply ships or distant warehouses. And one day, the service thinks the technology could even be able to build a small UAV at the press of a button. Carolyn Lambeth is a mechanical engineer for Combat Direction Systems Activity at Dam Neck, Virginia. She explained the future of 3D printing at the Navy on In Depth with Francis Rose.
