UK Defense Breakthrough: QinetiQ Flies First 3D Printed Part Made from Recycled Titanium

In a milestone for sustainable defense manufacturing, QinetiQ has completed the maiden flight of a 3D-printed structural component made from recycled titanium. The test, conducted at MOD Boscombe Down in Wiltshire, featured a 3D printed hinge mounted on an A109S helicopter being developed for the Empire Test Pilots School.

Flight-Critical Hardware from Scrap Metal

The printed hinge serves as a critical attachment point for an Air Data Boom — a high-precision external probe that measures airspeed and angle of attack. Failure during flight could trigger severe aerodynamic vibrations or cause the boom to snap, compromising the sensitive instrumentation data needed for pilot training.

Designed by QinetiQ and fabricated by Additive Manufacturing Solutions Limited (AMS Ltd.), the hinge was produced using titanium recycled from a decommissioned aircraft. This marks the first time flight-critical hardware has been successfully salvaged from scrap and returned to the sky through additive manufacturing.

97% Efficiency in Recycling

AMS Ltd. uses a proprietary atomization process that creates powder from recycled scrap metal, achieving 97% efficiency and minimizing material loss. The company has in-house laser and electron beam powder bed fusion capabilities.

According to QinetiQ, AMSs manufacturing process uses 93.5% less CO2e compared to traditional supply chains. This is significant because titanium production is notoriously energy-intensive and expensive.

Reducing UK Dependency on Foreign Titanium

Titanium ores are not rare, but the high reactivity of the metal with oxygen, nitrogen, and hydrogen at elevated temperatures makes production complicated and costly. China and Russia are currently the largest suppliers of aerospace-grade titanium globally.

By recycling titanium from scrap aircraft, the UK could significantly reduce its dependency on imported titanium. AMS Ltd. estimates that the UK could become largely self-sufficient if all titanium held in scrap aircraft was extracted for recycling.

Our testing and engineering expertise is helping to prove the technology which will reduce the UKs dependency on other nations for aerospace grade titanium, said Simon Galt, Managing Director Air at QinetiQ.

What This Means for 3D Printing

This breakthrough demonstrates that additive manufacturing can contribute to both sustainability goals and supply chain resilience. For defense applications, the ability to recycle and reuse titanium from retired aircraft could transform how military organizations approach parts availability and cost.

The success also validates the growing role of specialist metal AM companies in supporting defense contracts, bridging the gap between innovative research and real-world deployment.
