HII's Innovative Additive Manufacturing Breakthrough
HII (NYSE: HII) has achieved a significant milestone in the realm of shipbuilding at its Newport News Shipbuilding division. Recently, the team successfully installed the first valve manifold assembly that utilizes additive manufacturing technology on a new construction aircraft carrier. This innovative approach signifies a leap forward in the efficiency of shipbuilding processes.
Transforming Shipbuilding Processes
As the shipbuilding industry evolves, HII remains at the forefront by integrating additive manufacturing, commonly known as 3D printing, into its operations. The use of certified 3D-printed components stands to not only expedite the construction and delivery processes for the U.S. Navy but also enhance the quality of critical components significantly.
Details of the Additively Manufactured Valve Manifold Assembly
The valve manifold assembly, engineered to distribute fluid from a single source to multiple points aboard the ship, is installed in the pump room of the Gerald R. Ford-class aircraft carrier, named Enterprise (CVN 80). Measuring 5 feet in length and weighing in at an impressive 1,000 pounds, this assembly exemplifies the shipyard's commitment to leveraging additive manufacturing for enhanced construction capabilities. In collaboration with DM3D Technology, HII has successfully manufactured this component, marking a significant progression in shipbuilding methodology.
Future Implications for Additive Manufacturing in Shipbuilding
This initial success on the Enterprise (CVN 80) is only the beginning. HII is set to employ similar additive manufacturing techniques for future projects, including the upcoming Doris Miller (CVN 81) aircraft carrier. By opting for 3D printing over traditional casting methods, the shipyard aims to diminish schedule risks and boost overall efficiency in its shipbuilding processes.
Expert Insights on Innovation
Dave Bolcar, Vice President of Engineering and Design at NNS, expressed enthusiasm over this development: "What started as a proof of concept quickly turned into a tangible result that is making a meaningful difference to improve efficiencies in shipbuilding. The benefits of this innovation will extend well beyond Enterprise (CVN 80), as we incorporate our expertise in additive manufacturing into the fundamentals of shipbuilding." This perspective highlights the far-reaching impact of their innovative practices on future naval projects.
Enhancing Additive Manufacturing Efficiency
HII’s strides in additive manufacturing build on the shipyard's previous success as a certified supplier for additive components in Naval Sea Systems (NAVSEA) platforms. To date, the company has created over 55 additively manufactured parts that have already been installed on new construction vessels as well as those currently in active service. This year, plans are in place to install an additional 200 of these advanced parts, signaling a robust future for additive manufacturing in naval applications.
