# 3D-Printed Drone Turbojets Alloyed Speeds Up Custom Turbojet Development With 3D Printing By Ellen Smith | Written with AI assistance | Published 2026-10-25 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/3d-printed-drone-turbojets References: [aerospaceamerica.aiaa.org](https://aerospaceamerica.aiaa.org/u-k-startup-eyes-faster-design-production-process-for-turbojet-drone-engines)  Alloyed is moving small turbojet propulsion toward quicker custom builds for drone makers with a workflow that links digital modeling, [metal 3D printing](https://www.trendhunter.com/trends/Factory-scale-metal-printing) and computer-controlled machining. The Oxford, U.K., company can turn a base design into a flyable engine in roughly two months, and its 300-N engine has already flown and reached customers earlier this year. Production is rising on a 3-kilogram engine rated at 300 Newtons of thrust. Bench testing is underway on a 1,100-N version targeted for production by year-end. With [digital tooling](https://www.trendhunter.com/trends/Hybrid-advanced-manufacturing), engineers can update parts through simulation, stand tests and flights near Oxford without being locked into fixed tooling. A two-month path from adapted design to flight-ready hardware turns engine sourcing into a faster cycle for [drone builders](https://www.trendhunter.com/trends/lace-research-quadcopter), especially on one-way aircraft where cost and quick revisions matter. Digital tooling also broadens the pitch to reusable reconnaissance and other longer-range drones with mission-specific propulsion.
