Technology & Products
Key Products
3D-printed valve manifold assemblies; Copper-nickel deck drain assemblies; Large-scale metal AM components for submarines and aircraft carriers
Technological Advantage
Proprietary integration of metal AM processes (DED and LPBF) certified for naval use, protected by partnerships with technology providers like DM3D and AML3D; defensible due to regulatory approval and specialized expertise in marine alloys.
Differentiation
Value Proposition
Reduces lead times for critical naval components from months to weeks, cuts repair costs significantly, and establishes a decentralized, on-demand supply chain for fleet maintenance, enhancing operational readiness and reducing dependency on traditional casting methods.
How They Differentiate
HII holds NAVSEA certification for AM in naval shipbuilding, enabling direct production of certified parts for U.S. Navy vessels, unlike competitors who may supply equipment or services without such regulatory approval; focuses on large-scale DED for 1,000+ lb components vs. smaller LPBF systems from EOS or Renishaw.
