A essential facet of maritime security, aids to navigation, together with lighthouses and buoys, include hefty upkeep prices. The U.S. Coast Guard (USCG) has discovered an economical resolution by way of additive manufacturing. Partnering with the USCG’s Shore Infrastructure Logistics Middle and Command, Management, Communications, Computer systems, Cyber and Intelligence Service Middle, using 3D printing has revolutionized the restore and substitute of aids to navigation gear.

By using AM, the USCG can recreate elements which can be not commercially accessible, salvaging degraded or broken gear and returning it to serviceable situation. An exemplary case is the restoration of the VRB-25 optical system, essential for lighthouses alongside the U.S. shoreline. Regardless of preliminary efforts to exchange VRB-25s with LED methods for improved effectivity, the standard look and performance of VRB-25s remained unmatched. Leveraging 3D printing, out of date elements have been recreated to actual specs, enabling the manufacturing of 18 VRB-25s for reinstallation.
The advantages of 3D printing lengthen past navigation gear restore. In cases just like the Command Cyber Readiness Inspection, the place easy emergency shut-off change covers have been lacking, 3D printing provided a swift resolution, saving time and procurement prices. During the last two fiscal years, AM has saved over $650K in acquisition prices and reintegrated 164 repaired items of apparatus into stock.
To additional capitalize on this know-how, the AM Working Group plans complete trade coaching and collaboration with the Navy. With roughly twenty to thirty elements into account for 3D printing, starting from out of date elements to security covers, the USCG goals to boost its understanding of AM capabilities and optimize its software in maritime operations.
