Manufacturing requirements for large-scale, safety-critical metal structures are evolving - driven by increasing pressure on lead times, supply chains and performance in demanding environments. Wire Arc Additive Manufacturing (WAAM) is emerging as a viable, industrialised solution.

This talk explores how large-format WAAM is enabling the production of pressure-rated structural components for subsea and other corrosive, high-demand applications. With the ability to manufacture complex geometries faster than traditional casting or forging, WAAM is shifting what is possible for high-integrity applications.

We will present a world-first DED-Arc achievement: a pressure vessel for human occupancy, demonstrating how certified additive manufacturing can meet stringent safety requirements while accelerating delivery. The session will focus on what this means for real-world adoption, and how organisations can move from experimentation to deployment at scale.
