The future of UK Defence: Why we must invest in drones and 3D printing now
The strategic imperative for 3D printing and drone investment
The UK’s defence landscape is facing rapid change, with emerging technologies like 3D printing and drones reshaping how military operations are conducted. Recent conflicts, notably in Ukraine, have demonstrated the advantages of these technologies, not only for agility and responsiveness but also for maintaining resilience in disrupted supply chains. According to Sir Mike Wigston, Chief of the Air Staff, the Royal Air Force’s focus on “on-demand” drone production can “confuse and overwhelm adversaries,” showcasing the advantages of this technology in asymmetric conflicts.
Lessons from Ukraine: Low-cost, high-impact solutions
The conflict in Ukraine has fundamentally changed modern warfare. Ukraine’s military has effectively used drones and 3D printing to compensate for its limited access to traditional manufacturing and advanced weaponry, using locally produced 3D-printed drone parts to adapt commercially available drones for precision strikes and anti-armour missions. By adding 3D-printed fins to existing munitions, Ukrainian forces have transformed standard drones into tactical assets, showcasing the flexibility that 3D printing can offer on the battlefield.
In the UK, investing in similar capabilities could lead to a more adaptable, cost-effective defence strategy - supporting rapid parts production and operational resilience, reducing dependence on traditional supply chains, particularly in hostile environments. Charlotte Robinson, Innovation Team Lead at UK Strategy Command said a series of global hubs that can rapidly print and provide assured quality parts for us and our allies could be “crucial in terms of platform availability” but also bring with it a host of other benefits including “quick access to spares, reduction of the need to stockpile as well as significant cost savings and environmental benefits.”
Strengthening international partnerships
To enhance interoperability within international partnerships, the UK should increase support for NATO and other international UAV initiatives, which aim to create an integrated drone network among member states. The UK’s involvement not only strengthens collective defence but also ensures that it can operate seamlessly its allies. The Royal Navy’s recent trials of naval drones underscore this commitment to shared, agile defence solutions. This partnership allows the UK to lead in innovation while contributing to multi-domain capabilities across air, land, and sea.
This closely aligns with the UK’s new drone strategy spending an additional £4.5 billion over the next decade on new military drones, aiming to turn Britain into a “world leader” in drone manufacturing to “rapidly” equip its armed forces with advanced air, land and sea based uncrewed systems in the process. Additive manufacturing is not just about military capability – it's about creating a resilient, innovative defence industrial base that can respond rapidly to emerging threats while supporting thousands of high-skilled jobs across the UK.
3D printing technology
HP Inc. has been active in leveraging its 3D printing technology for drone manufacturing, notably through collaborations with companies like Unusual Machines. HP’s Multi Jet Fusion (MJF) technology has been chosen by Unusual Machines to produce FPV (First-Person View) drones, focusing on enhancing manufacturing efficiency and product quality. As François Minec, Head of Polymers, HP 3D Printing, points out: “MJF technology is swiftly being adopted across multiple industries, significantly enhancing drone performance." MJF technology is particularly suited for the drone industry due to its ability to produce strong, lightweight parts with complex geometries. This is critical for drones that must be both robust and agile.
Key reasons for immediate action
Geopolitical pressures: With evolving threats from state and non-state actors, the UK must prioritise flexible, adaptive solutions. Drones and 3D printing offer scalable, efficient options for diverse conflict scenarios.
Competitive defence innovation: Other countries are investing heavily in similar technologies. To maintain a strategic edge, the UK must stay competitive.
Allied interoperability: Supporting international drone initiatives allows the UK to advance its UAV capabilities while benefiting from shared intelligence and research.
Ukraine's effective use of drones has demonstrated how smaller nations can develop asymmetric advantages. For countries like the UK, investment in these technologies is not optional – it's essential for maintaining credible deterrence in the modern battlespace.
By investing in 3D printing to support drone productions, the UK can enhance its resilience, promote agile responses, and strengthen its standing within international partnerships. These technologies represent not only an advancement in defence but a commitment to modern, flexible warfare that is essential in today’s uncertain geopolitical climate.
