What's Happening?
The Naval Undersea Warfare Center (NUWC) Division, Keyport, has become the first Warfare Center to receive official approval from the Naval Sea Systems Command (NAVSEA) for a metal powder bed fusion additive manufacturing procedure. This qualification
allows the center to produce tactical- and shipboard-level parts using 17-4PH stainless steel, a material commonly used in the Navy. The approval marks a significant shift from traditional manufacturing to on-demand production capabilities, enabling the Navy to print parts as needed, rather than maintaining large inventories. The initiative began as a project to address supply chain constraints for legacy parts and has evolved into a formal qualification project.
Why It's Important?
This development represents a major advancement in military manufacturing capabilities, allowing for more efficient and flexible production of critical components. By adopting additive manufacturing, the Navy can reduce dependency on traditional supply chains, which can be slow and costly. This capability is particularly valuable for maintaining operational readiness and reducing downtime for repairs. The qualification also sets a precedent for other commands to adopt similar technologies, potentially transforming the Navy's approach to manufacturing and logistics.
What's Next?
Following this qualification, NUWC Division, Keyport plans to expand its additive manufacturing capabilities to include other materials, such as 316L stainless steel, which has broader applications for ship and submarine maintenance. The command is also working on developing in-situ hardware to monitor the printing process for real-time quality assurance. These advancements could lead to further integration of additive manufacturing across the Navy, enhancing the efficiency and effectiveness of military operations.
