Executive Summary: From Bracket to Spar — Wire-DED Reaches Airframe Scale
January 28, 2026 – Aerospace additive manufacturing has spent the better part of a decade proving itself on secondary structures: brackets, fittings, duct supports. Impressive as topology-optimized components are, they never threatened the core of aerospace production — the multi-story forging press and its 90%-waste machining workflows.
That boundary is now shifting. Airbus has begun serial integration of wire-Directed Energy Deposition (w-DED) titanium parts into the A350 Cargo Door Surround — and confirmed plans to scale the technology to structural components up to 7 meters for future programs including wings and landing gear. Simultaneously, America Makes launched the Powder Alloy Development for Additive Manufacturing (PADAM) 2.0 initiative, a $6M program targeting supply chain resilience for high-temperature refractory alloys.
These are not first-of-kind events in wire-AM aerospace — that milestone belongs to Norsk Titanium, whose Rapid Plasma Deposition parts earned FAA structural certification for the Boeing 787 Dreamliner in 2017. What's new is the scale (7m vs. sub-1m fittings) and the intent (primary airframe structure vs. secondary support brackets). The transition from component substitution to structural fabrication is accelerating.
Prior Art: Wire-AM in Aerospace Is Not New
Before assessing the Airbus announcement, context is essential:
Norsk Titanium / Boeing 787 (2017): First FAA-certified additively manufactured structural titanium parts on a commercial aircraft. Wire-based RPD process, currently supplying ~30 serial production part numbers. Norsk signed a Master Supply Agreement with Airbus in April 2024 for A350 production. (Source: Norsk Titanium press release, June 2017; Metal AM magazine, April 2025)
Cranfield University WAAM (2010s–present): Pioneered large-scale Wire Arc Additive Manufacturing research, including Bombardier landing gear assemblies as demonstrators. Academic, not yet serial production.
GE Aviation LEAP Fuel Nozzle (2015): While powder-bed and not wire, it established the precedent for flight-critical AM parts in propulsion — over 100,000 units produced. The industry's most-cited proof point.
Airbus A350 Existing AM Adoption: Airbus has used LPBF titanium parts on the A350 since the mid-2010s, primarily for cabin brackets and secondary structures. The w-DED shift targets larger, more structurally significant components.
What's actually new in January 2026: The dimensional threshold (7m), the application scope (primary airframe forging replacement), and the transition from pilot qualification to serial integration on an in-production aircraft (A350 Cargo Door Surround).
The Market Signal: Scale and Rate Cross the Threshold
The defining signal of late January comes from Airbus's own newsroom, which confirmed serial integration of w-DED parts on the A350 and outlined the technology's trajectory:
Scale: Structural titanium components up to 7 meters in length — an order of magnitude beyond typical LPBF build volumes (sub-600mm). (Source: Airbus newsroom, January 2026)
Rate: Deposition rates of several kilograms per hour, compared to hundreds of grams per hour for powder-bed systems. (Source: Airbus newsroom)
Buy-to-Fly Improvement: Traditional forging-to-machining workflows waste 80–95% of raw titanium as chips. Near-net-shape w-DED dramatically reduces this ratio. (Source: Airbus newsroom; industry standard figures)
Lead Time: Airbus states that w-DED eliminates the 1–2 year tooling lead time required for die forgings, replacing it with weeks of programming and print time. Specific percentage reduction claims require caution — actual cycle times for 7m parts in serial production are not yet public.
This development targets wings and landing gear on future programs — a direct challenge to the forged billet supply chain. However, targeting and delivering certified serial parts are separated by qualification timelines that historically take 3–7 years in aerospace. The A350 Cargo Door Surround integration is the concrete, present-tense milestone; the wing/landing gear ambition is a stated roadmap.
Strategic Deep Dive: The Wire vs. Powder Bifurcation
The Airbus announcement clarifies a developing divergence in metal AM's application map:
Wire-DED is claiming the "Long and Strong" structural market — spars, ribs, door surrounds, and eventually wing components. The physics favor it: wire feedstock enables kg/hr deposition rates, and the multi-axis robotic arm format accommodates meter-scale linear geometries without enclosed build chambers.
Large-Format LPBF is claiming the "Round and Complex" propulsion and thermal management market — combustion chambers, nozzles, heat exchangers. Data from the Beijing Commercial Aerospace Expo (January 27) shows AVIC Mait deploying multi-laser SLM systems with 1000mm+ build volumes, backed by 800 tons/year of powder capacity.

Both pathways squeeze the traditional forging, casting, and brazing supply base — but through different mechanisms. Wire-DED competes on material efficiency and lead time against forgings. Large-format LPBF competes on part consolidation and geometric complexity against castings and assemblies.
Counter-signal: This bifurcation is cleaner in theory than in practice. Wire-DED parts still require significant post-machining (the Norsk Titanium 787 parts are explicitly described as "near-net-shape" requiring finish machining). And Norsk Titanium's Q1 2025 operational update revealed revenue of only $0.6M against a $150M 2026 target, with customer delays pushing key transitions to H2 2025 — a reminder that qualification timelines, not deposition rates, remain the binding constraint.

Industry Context: The Feedstock Question
Megastructure-scale AM requires proportional feedstock supply. Two concurrent developments address this, though from different angles:
America Makes: PADAM 2.0
America Makes launched PADAM 2.0 (Powder Alloy Development for Additive Manufacturing), a $6M initiative funded by the Air Force Research Laboratory. The program targets high-temperature refractory alloys — not titanium specifically — across three topic areas: maturing existing alloy systems, advancing novel/emerging alloys, and conducting end-to-end supply chain assessment from mine to qualified part. (Source: America Makes press release, February 4, 2026)
This is important but narrower than the original reporting suggested: PADAM 2.0 addresses the refractory alloy gap for defense/propulsion applications, not the titanium wire supply for airframe w-DED. The two are complementary but distinct supply chain challenges.
Asian Vertical Integration
Chinese powder producers continue aggressive capacity expansion. Kaihe Technology secured Series A funding for "short-process" titanium powder production targeting 30% cost reduction. Yunhuo Materials is standardizing niobium powders for space applications. (Source: Company PR) The pattern is consistent with China's broader strategy of vertical integration from raw material to finished part — a "Mine-to-Part" approach that contrasts with the Western model of specialized supply chain tiers.
The Circular Economy Signal
PyroGenesis received a repeat order for titanium powder derived from machining off-cuts — a modest but meaningful validation of circular feedstock in defense supply chains.
Outlook: What to Watch
Near Term (2026): The concrete metric is whether Airbus expands w-DED from the A350 Cargo Door Surround to additional part numbers and programs. Norsk Titanium's target of 120 serial production parts by year-end is the quantitative benchmark for wire-DED maturation. The "85% lead time reduction" claim requires validation against actual serial production data.
Medium Term (2027–2028): The competitive battleground shifts to feedstock. As build volumes grow, the strategic asset transitions from the deposition head to the atomizer (for powder) and the wire drawing facility (for wire-DED). National capacity for flight-grade titanium feedstock at tonnage scale becomes a matter of industrial policy, not just commercial competition.
Risk Factors: Certification timelines remain the binding constraint. Airbus's own framing — "step by step, from the A350 w-DED parts and into more critical applications" — signals measured progression, not overnight disruption. The 7-meter capability is real; serial production of 7-meter flight-qualified parts is a multi-year journey.
