Airbus Starts Serial Production of Large Titanium 3D-Printed A350 Parts
Airbus initiates serial integration of large titanium 3D-printed parts for the A350 using w-DED technology in partnership with Norsk Titanium.
This article is based on an official press release from Airbus and additional industry data regarding Norsk Titanium.
As of January 2026, Airbus has officially commenced the serial integration of large-scale, 3D-printed titanium components into the A350 program. According to an official company statement, this milestone focuses on the Cargo Door Surround area of the Commercial-Aircraft, marking a decisive shift from traditional Manufacturing methods to advanced Wire-Directed Energy Deposition (w-DED) technology.
This development represents a significant evolution in aerospace manufacturing. While 3D printing (additive manufacturing) has been used previously for smaller brackets and non-structural cabin parts, the move to w-DED allows for the production of large, high-load-bearing structural components. Airbus indicates that this transition is driven by the need to reduce raw material waste, shorten production lead times, and prepare for the high-rate demands of future aircraft programs.
Historically, the aerospace sector has relied heavily on “Powder Bed Fusion” for additive manufacturing. While precise, this method is constrained by the size of the printer’s bed, typically under two feet, and relatively slow production speeds measured in grams per hour. In its recent announcement, Airbus detailed its adoption of w-DED to overcome these limitations.
The w-DED process utilizes a robotic arm to feed titanium wire into a laser or plasma beam, melting the material layer-by-layer to build a part. According to technical details released by Airbus, this method offers two primary advantages over powder-based systems:
The parts currently being installed on the A350 Cargo Door Surround are produced as “near-net shapes.” This means the component is printed to a rough outline of the final specification and then machined to exact tolerances. This hybrid approach combines the speed of additive manufacturing with the precision of traditional machining.
A primary driver for this technological shift is the drastic reduction in material waste, measured in the industry by the “Buy-to-Fly” ratio. This ratio compares the weight of the raw material purchased to the weight of the final finished part.
According to industry data and Airbus’s manufacturing analysis:
By reducing the amount of titanium required, Airbus aims to lower both environmental impact and production costs. Furthermore, the digital nature of the process reduces lead times from months to weeks, as it eliminates the need to create physical molds or dies associated with forging.
The successful integration of these parts is supported by a partnership with Norsk Titanium. Following a Master Supply Agreement signed in April 2024, Norsk Titanium has utilized its proprietary Rapid Plasma Deposition (RPD) technology to supply these structural components. This collaboration has been instrumental in moving the technology from a testing phase to serial mass production. Airbus has stated that the A350 application serves as a “stepping stone” for more ambitious future projects. The scalability of w-DED is considered critical for two upcoming challenges:
The adoption of w-DED for the A350 Cargo Door Surround signals that Airbus is moving aggressively to close the gap with competitors in the additive manufacturing space. Boeing has utilized Norsk Titanium’s RPD parts on the 787 Dreamliner since approximately 2017 to reduce costs. However, Airbus’s application appears to target larger and more complex structural areas, suggesting a strategy of “catch-up and scale-up.”
Furthermore, this move validates the broader industry trend toward “Near-Net Shape” manufacturing. As geopolitical and supply chain instabilities continue to affect the availability of raw titanium, technologies that reduce material consumption by up to 90% are no longer just “green” initiatives, they are strategic necessities for maintaining production stability.

Boeing Retires Final 787-8 Test Aircraft ZA004 After 16 Years
Boeing retires ZA004, the last 787-8 test aircraft, after 16 years of flight testing and key contributions to engine and battery system improvements.
This article is based on an official press release from Boeing.
After nearly 16 years of service as a dedicated “flying laboratory,” Boeing has officially retired ZA004 (Registration N7874), the last remaining flight-test aircraft from the original 787-8 Dreamliner program. According to an official announcement from Boeing, the aircraft concluded its final mission on February 11, 2026, marking the transition of the Dreamliner family from a developmental phase into a fully mature operational stage.
The aircraft, which accumulated over 2,250 flight hours across more than 670 test flights, was flown one last time from Boeing Field (KBFI) in Seattle to Pinal Airpark (KMZJ) in Marana, Arizona. There, it will be stored and likely used for parts reclamation to support active fleets.
ZA004 holds a unique place in the history of the 787 program. As the fourth Dreamliner ever built, it was originally manufactured for Northwest Airlines prior to that carrier’s merger with Delta Air Lines in 2008. However, due to early program delays and the subsequent merger, the airframe was never delivered to a commercial customer. Instead, Boeing retained the aircraft, repurposing it as a dedicated testbed, a role it fulfilled for its entire operational life.
Unlike its siblings in the original test fleet, ZA001 through ZA006, ZA004 remained in service significantly longer. While the first three test aircraft were donated to museums and others were scrapped, ZA004 continued to validate new technologies for over a decade. John Murphy, the 787 Chief Project Engineer, highlighted the rarity of such a long service life for a test asset.
“Sixteen years of service with The Boeing Company, that’s a legacy few test airplanes achieve.”

Throughout its tenure, ZA004 served as a workhorse for systems reliability and propulsion testing. Boeing data indicates the aircraft was central to several critical engineering milestones that allowed the global 787 fleet to grow to over 1,100 aircraft.
The aircraft was the primary platform for testing upgrades to the Rolls-Royce Trent 1000 engine. It played a vital role in certifying the “TEN” and “XE” improvement packages, which were designed to resolve durability issues and extend time-on-wing for airline operators. Furthermore, following the global grounding of the 787 fleet in 2013, ZA004 was instrumental in validating the redesigned battery containment system and updated power distribution software, paving the way for the fleet’s return to service. In 2014, Boeing utilized ZA004 for its ecoDemonstrator program. During this phase, the aircraft tested more than 25 new technologies aimed at reducing noise and improving fuel efficiency. These tests included aerodynamic enhancements and software designed to optimize flight paths, many of which have since been integrated into commercial operations.
The retirement flight on February 11, 2026, was piloted by Captains Heather Ross and Craig Bomben. In a symbolic nod to the aircraft’s history, these were the same two pilots who sat in the cockpit for ZA004’s maiden flight on February 24, 2010.
According to Boeing, the decision to retire the aircraft was driven by economics. As the airframe approached a major heavy maintenance check (D-check), the company determined that maintaining a dedicated -8 testbed was no longer cost-effective given the maturity of the 787 platform.
“To the casual observer it looks like an old airplane, but it’s always been the future.”
Captain Heather Ross, Boeing Chief Pilot (via Boeing)
The retirement of ZA004 signals a definitive shift in the lifecycle of the 787 program. For years, the presence of a dedicated test airframe allowed Boeing to rapidly prototype fixes and upgrades, most notably during the battery crisis of 2013. The decision to retire the asset without a direct replacement suggests that Boeing views the 787-8 platform as sufficiently stable, requiring fewer experimental resources than it did during its volatile early years.
While the aircraft will no longer fly, its components will likely continue to keep other Dreamliners in the air, serving as a donor source for a fleet that now spans the globe. This move aligns with broader industry trends where mature airframe programs rely on operational data from airline partners rather than maintaining expensive, dedicated manufacturer test fleets.

RTX Boosts PCB Production with AI Quality Control in Puerto Rico
RTX integrates AI inspection at its Puerto Rico facility, increasing PCB output by 14% and halving defects while reducing inspection time.
On February 10, 2026, RTX (formerly Raytheon Technologies) announced a significant leap in manufacturing efficiency at its Collins Aerospace facility in Santa Isabel, Puerto Rico. The aerospace giant has successfully integrated artificial intelligence into its quality control processes, specifically targeting the production of printed circuit boards (PCBs). According to the company, this initiative has resulted in double-digit increases in production output and a substantial reduction in defect rates.
The Santa Isabel facility, now designated as a “lighthouse” site for RTX’s global operations, serves as a proving ground for digital technologies. By implementing AI-enabled automated optical inspection (AOI) systems, the factory aims to overcome the inherent limitations of human inspection when dealing with the microscopic complexity of modern aviation electronics.
Printed circuit boards are the nervous system of modern aircraft, controlling everything from navigation to engine performance. A single board, often no larger than a standard sheet of paper, contains thousands of minute components. Ensuring 100 percent compliance with strict aviation standards is a monumental task for human inspectors.
Jorge Vazquez, the site leader at the Collins Aerospace facility in Santa Isabel, highlighted the difficulty of manual verification in the company’s announcement:
“Imagine ensuring 100 percent compliance with standards, on thousands of components. It’s almost impossible for the human eye alone.”
Jorge Vazquez, Site Leader, Collins Aerospace Santa Isabel
To address this, the facility has deployed computer vision systems that scan boards with speed and accuracy that exceed human capabilities. RTX reports that the AI system acts as a “tireless quality control expert,” identifying missing, misaligned, or incorrect components instantly.
The integration of these digital tools has yielded measurable operational improvements. According to data released by RTX, the Santa Isabel facility has recorded the following metrics since the implementation of the new systems: The advancements in Puerto Rico are part of RTX’s broader “Connected Factory” initiative. This strategy involves linking systems, machinery, and products via a proprietary data platform to identify bottlenecks across the company’s global footprint. The Santa Isabel site previously introduced a “Smart Line” in 2019, a fully automated production line that laid the groundwork for the current AI integration.
Beyond optical inspection, the facility is currently rolling out Real-Time Location Services (RTLS). This technology functions similarly to consumer tracking devices, such as AirTags. By attaching tags to individual circuit boards, factory managers can monitor the flow of materials through the production line in real-time.
This system eliminates the need for manual scanning, which RTX notes is often slow and prone to error. The data gathered allows for immediate workflow adjustments, further streamlining the manufacturing process.
The designation of the Puerto Rico facility as a “lighthouse” site suggests that RTX intends to standardize these AI-driven methodologies across its global manufacturing network. In the high-stakes aerospace sector, where supply chain delays can ground fleets, the ability to reduce inspection time by 66% (from 30 to 10 minutes) represents a critical competitive advantage.
Furthermore, the shift toward AI-assisted inspection addresses a common industry challenge: the cognitive fatigue associated with repetitive, high-precision tasks. By offloading the visual scanning to computer vision algorithms, human operators are freed to focus on complex problem-solving and process improvement, a shift that aligns with the broader Industry 4.0 trend of augmenting rather than replacing the skilled workforce.
