The U.S. Navy is delving into the integration of 3D printing technology into its shipbuilding programs, aiming to address delays caused by various operational challenges, as highlighted at the Sea-Air-Space trade show. Mark Massie, a program manager at the Naval Sea Systems Command supervising additive manufacturing, showcased metal parts that were swiftly produced, underlining the readiness of metal additive manufacturing for practical deployment.
An assessment of the Navy’s shipbuilding programs revealed significant delays attributed to workforce shortages and supply chain disruptions exacerbated by the COVID-19 pandemic. Leveraging 3D printing technology, such as the Additive Manufacturing Center of Excellence in Virginia, is crucial to the Navy’s strategic plans for constructing submarines and enhancing operational efficiency.
Despite the advancements in additive manufacturing, Massie expressed cautious optimism, citing three primary challenges. The first hurdle involves expanding the pool of contracted companies. Following the rapid procurement of 3D-printed parts from eight vendors using other transaction authority, the Navy aims to engage more firms to bolster its additive manufacturing capabilities.
The second challenge lies in streamlining the acquisition process for 3D-printed materials within the Pentagon. Massie emphasized the need to simplify the purchasing mechanism, transitioning it to mirror traditional material procurement methods for seamless integration.
Lastly, the Navy is focused on conducting rigorous testing of acquired 3D-printed parts to ensure their reliability and compatibility with naval operations. While the technology shows promise in expediting repairs and maintenance at sea, comprehensive field testing is vital before widespread adoption on naval vessels.
Industry leaders like Chris Kastner from HII underscored the regulatory hurdles in approving 3D-printed parts for naval applications. Despite the challenges, Kastner and Navy officials are optimistic about the increasing approvals for additive manufacturing in shipbuilding.
With a clear directive from Pentagon leadership to leverage 3D printing for low-risk components, such as critical spare parts, the Navy is making headway in integrating this innovative technology across its fleet. The planned installation of 3D printers on various naval vessels signals a shift towards greater confidence in additive manufacturing for maritime operations.
