For years, metal additive manufacturing in aerospace has been associated with powder-bed fusion: high-value parts, intricate geometries and relatively small build envelopes. But the next scale story in structural titanium may come from a different branch of AM entirely.
Airbus is now serially integrating large wire-directed-energy-deposition parts into the A350 cargo-door surround. The parts are printed by a qualified supplier using plasma w-DED, ultrasonically inspected, machined to final dimensions and installed in Airbus factories.
The process is attacking a different problem
Laser powder-bed fusion excels where geometric complexity, internal channels or part consolidation justify relatively expensive build time. Wire DED attacks a different bottleneck: producing large metallic preforms close to final shape without starting from a massive forging or plate.
Airbus says its w-DED work can produce structural titanium parts up to seven meters long and increase deposition from the hundreds-of-grams-per-hour range typical of powder-bed systems to several kilograms per hour. That is a fundamentally different industrial scale.
Titanium makes the economics unusually powerful
Titanium is attractive in aircraft because of its strength-to-weight ratio and compatibility with carbon-fiber structures, but it is expensive and difficult to process. Conventional routes can begin with substantially more material than ends up in the aircraft. Airbus states that traditional methods may require recycling 80% to 95% of the titanium originally purchased for some parts.
Wire DED changes that equation by building a near-net-shape blank. The final machining operation remains essential, but far less metal may need to be removed. In this use case, additive manufacturing is not replacing machining; it is changing what machining starts from.
Tooling and lead time matter too
Airbus notes that large die-forging tooling can take up to two years to create, while a digitally defined printed preform can reduce the route to weeks. That makes w-DED especially interesting during development programs, low-to-medium-rate production, supply disruptions and design phases where geometry may still evolve.
The real bottlenecks move downstream
High deposition rate does not eliminate industrial friction. Large aerospace DED parts still require process control, heat-management strategy, machining, nondestructive inspection and a qualification path. Airbus’ A350 example is revealing because it includes the entire chain: qualified deposition, ultrasonic inspection, machining and final installation.
That means the investable or strategically scarce assets may not be the deposition head alone. They may include qualified titanium wire, robotic integration, large-envelope process knowledge, NDT capacity, finishing capacity and the certification evidence connecting them.
