Craig Pyser, chairman of AMUKThe UK defence sector is failing to capitalise on transformative manufacturing capabilities that could revolutionise supply chain resilience and cut costs by £110 million, an industry leader warned earlier this week. As defence professionals gather at the industry’s biggest conference,
DSEI UK, this week, additive manufacturing (AM) experts say the sector's unfamiliarity with modern 3-D printing applications is blocking access to production-ready capabilities.
Craig Pyser, chairman of AMUK, the AM industry’s trade association, cited the Ministry of Defence’s new
Advanced Manufacturing Strategy highlights AM as critical for strengthening supply chain resilience. He said: “The MoD’s own strategy references a Defence Innovation Unit report estimating that if 15% of the defence inventory were produced by using AM, the net financial benefit to the MoD would be £110 million over the next 15 years.
“There are also ongoing annual benefits of £35.5 million but those figures will only materialise if we bridge a critical knowledge gap between our industry and procurement teams commissioning large scale defence contracts. The technology exists and, importantly, the companies exist. We have UK firms delivering production-scale AM right now, but there is a fundamental knowledge gap preventing the sector from maximising these capabilities. Education is vital and we all have a role to play in shaping the conversation.”
The warning comes as the Government has committed to increasing defence spending by £2.9 billion in 2024, with plans to reach 2.5% of GDP by 2027. This investment is driving demand for more resilient supply chains that can adapt quickly to changing requirements and reduce dependence on vulnerable international suppliers.
Advanced AM capabilityMr Pyser is also chief executive of Portsmouth-based
AMufacture, which he co-founded with former naval architect and Olympic sailor Will Howden. The company has invested significantly in advanced HP Multi Jet Fusion printer technology and automation, delivering projects for clients across the aerospace, automotive, medical and marine sectors. It is based in Portsmouth's industrial cluster near major defence contractors including BAE Systems, Airbus and Lockheed Martin, representing the type of UK capability the MoD strategy seeks to leverage.
He added: “The challenge is not the technology, it is that decision-makers are still thinking about 3-D printing as it was 10 years ago, not as the production manufacturing process it has become. The MoD strategy acknowledges that obsolescence was identified as the ‘number one’ supply issue. With the MoD managing an inventory that currently exceeds 1.3 million items, the opportunity for AM to provide alternative sources of supply for obsolescent items is substantial.”
UAV and drone components represent a particularly compelling application for AM, where rapid iteration and on-demand production can provide tactical advantages. The US military has already demonstrated 3D-printed drone systems built and deployed in under 24 hours, highlighting the operational benefits of the technology.
Mr Pyser argues that the defence sector needs urgent education about modern additive manufacturing capabilities, particularly as the MoD shifts from ‘just-in-time’ to ‘just-in-case’ supply chain models that require more flexible manufacturing approaches.
“There is a real wealth of 3-D printing talent in the UK. We need to shout louder about what we can achieve when it comes to modern-day production and the wide array of cost, environmental and performance benefits additive manufacturing can deliver. If defence switches on to the fact, it can push for those £110 million savings while also driving massive economic impact to some of the country’s fastest-growing and exciting manufacturers.”
