GKN Aerospace and USAF Launch $8.4M Additive Manufacturing Program

This article is based on an official press release from GKN Aerospace.

On April 13, 2026, GKN Aerospace and the U.S. Air Force Research Laboratory (AFRL) announced the launch of a collaborative $8.4 million manufacturing initiative. The program, officially named TITAN-AM (Titanium Industrialization and Technology Advancement for Near-net Additive Manufacturing), is designed to industrialize and advance 3D printing technologies for large-scale aerospace structures.

According to the official press release, the partnership will focus heavily on Laser Metal Deposition with Wire (LMD-w) technology. By shifting away from traditional subtractive manufacturing methods, the initiative aims to make the production of next-generation titanium aerostructures faster, more sustainable, and highly efficient.

The TITAN-AM program will be executed at GKN Aerospace’s Global Technology Centre located in Fort Worth, Texas. We understand from the announcement that the project is expected to yield significant advancements for both commercial aviation and domestic defense supply chains by proving the viability of additively manufactured titanium components in operational environments.

The TITAN-AM Program and LMD-w Technology

The core of the $8.4 million TITAN-AM investment centers on maturing Laser Metal Deposition with Wire (LMD-w). As detailed in the program’s background materials, LMD-w is a directed energy deposition (DED) process that utilizes a high-powered laser to melt a continuously fed titanium wire, building complex structures layer by layer.

Titanium is a highly sought-after material in the aerospace sector due to its exceptional strength-to-weight ratio and resistance to corrosion. However, traditional manufacturing requires machining parts from massive titanium blocks. According to industry data cited in the announcement, conventional subtractive manufacturing can result in a “Buy-to-Fly” ratio of up to 95 percent, meaning that up to 95 percent of the raw titanium is machined away as scrap waste. LMD-w technology drastically reduces this material waste while simultaneously shortening production lead times.

The TITAN-AM program aims to accelerate the readiness of LMD-w technology and demonstrate its value on operational titanium structural components for both defense and commercial aerospace platforms, according to the GKN Aerospace announcement.

Five Critical Focus Areas

To successfully qualify LMD-w for rigorous aerospace structural applications, the press release outlines five specific focus areas for the TITAN-AM program:

• Industrialization: Scaling the LMD-w processes to accommodate large-scale titanium aerostructure components.
• Material Datasets: Developing comprehensive and robust titanium material datasets to guarantee structural performance, safety, and long-term reliability.
• Advanced Simulation: Improving digital simulation capabilities to optimize structural designs and accurately predict manufacturing outcomes before physical printing begins.
• Inspection Techniques: Pioneering Non-Destructive Inspection (NDI) methods specifically tailored for the unique properties of additive manufacturing processes.
• Practical Demonstration: Validating the technology by physically manufacturing and rigorously testing selected aerospace structural components.

Leveraging Fort Worth’s “Cell 3” Infrastructure

The execution of the TITAN-AM program relies heavily on existing infrastructure at GKN Aerospace’s Fort Worth facility. The company will leverage its massive “Cell 3” additive manufacturing system, which was officially commissioned in June 2023.

According to the provided background data, Cell 3 is recognized as the world’s largest known laser-directed energy deposition additive manufacturing cell. The system is equipped with a 20-kilowatt laser, features up to 10 axes of motion, and operates within a massive inert environment. This setup is capable of printing titanium components up to 5 meters (over 16 feet) in length, making it uniquely suited for the large-scale goals of the AFRL partnership.

Partner Backgrounds and Expertise

Both partners bring decades of specialized experience to the TITAN-AM initiative. GKN Aerospace noted in its release that it possesses over 20 years of experience in additive technologies. The company is already utilizing 3D printing in serial production for commercial-aircraft; for instance, GKN produces the additively manufactured fan case mount ring for the Pratt & Whitney GTF (Geared Turbofan) engine family, which currently operates on the Airbus A220 and Embraer E195-E2.

The U.S. Air Force Research Laboratory (AFRL) has been researching fusion-based additive manufacturing for aerospace alloys since the late 1990s. The military’s ongoing investment in this sector is driven by strategic imperatives: maintaining and modernizing legacy weapon systems, reducing reliance on foreign-sourced raw materials, and fortifying the domestic defense industrial base.

AirPro News analysis

At AirPro News, we view the TITAN-AM initiative as a critical step in bridging the aerospace industry’s “Valley of Death”, the notoriously difficult regulatory and financial transition from successful prototype to certified, flight-ready hardware. By explicitly focusing on the creation of robust material datasets and specialized non-destructive inspection (NDI) techniques, GKN and the AFRL are directly addressing the primary hurdles to Federal Aviation Administration (FAA) and Department of Defense (DoD) certification.

Furthermore, the broader supply chain implications cannot be overstated. The U.S. defense sector has faced persistent bottlenecks in traditional heavy forging and casting. By transitioning to near-net additive manufacturing, the industry can onshore critical manufacturing capabilities, allowing the U.S. to build large-scale aircraft components locally and on-demand. Coupled with the massive reduction in raw titanium waste, this shift represents a significant leap forward for both supply chain resilience and aerospace sustainability.
