Additive manufacturing in Marine is the use of additive manufacturing in maritime and naval applications: ship propellers, valve and pump components, large structural elements for naval vessels, and offshore platform spares.
Why AM fits Marine: Marine adopts AM where parts are large, low-volume, and corrosion-resistant alloy intensive. WAAM (DED-Arc) is the standout process: AML3D, MX3D, and Norwegian shipyards have produced multi-meter propellers, manifolds, and structural brackets where casting lead times exceeded ship-yard schedules.
Common AM processes: DED-Arc (WAAM) for large structures, PBF-LB for valves and pump components. Typical materials: nickel-aluminum bronze, super duplex stainless, copper-nickel, Inconel.
