Shipbuilders at Newport News Shipbuilding have made a significant advance in construction technology. They successfully installed the first valve manifold assembly produced by 3D printing on a new aircraft carrier, the USS Enterprise (CVN 80). This specialized assembly is designed to distribute fluid from a single source to multiple points on the ship and measures around 5 feet in length, weighing 1,000 pounds.
The introduction of 3D printed parts is expected to accelerate the construction and delivery processes for vessels intended for the U.S. Navy. By using certified components, shipbuilders can reduce lead times and enhance manufacturing quality for critical elements of the ships.
Collaboration with DM3D Technology led to the production of the manifold body, showcasing the shipyard’s commitment to integrating additive manufacturing into its processes. Looking ahead, similar assemblies for the USS Doris Miller (CVN 81) will also utilize this technology, replacing traditional casting methods to mitigate risks and improve operational efficiency.
Dave Bolcar, vice president of engineering and design at Newport News Shipbuilding, emphasized that the transition from proof of concept to practical application is not just improving the shipbuilding process for the Enterprise, but also laying the groundwork for future projects. To date, the shipyard has implemented more than 55 additively manufactured parts across various vessels, with plans to produce over 200 additional parts this year.
This innovation reflects a broader trend in the shipbuilding industry, as more companies adopt advanced manufacturing techniques to streamline operations and meet the needs of modern naval construction.
