The world's fastest drone is 3D-printed

What happens when engineering-driven ideas meet 3D printing and a clear goal? You get a completely homemade drone that just reclaimed the title of the world's fastest quadcopter. The video below follows South African engineer and YouTuber Luke Maximo Bell and his father as they push their homemade drone, the Peregreen V4, to its limits. The goal: to beat the rival team's speed record. What makes the project unusual is its accessibility. Instead of expensive, specialized industrial tools, the Peregreen V4's body was printed in one piece using a consumer-friendly 3D printer, the Bambu Lab H2D. By combining different materials, they achieved a balance between strength and aerodynamics. The result speaks for itself: the drone reached a verified average speed of about 657 km/h over two laps in opposite directions, which was clearly enough to reclaim the Guinness World Record. In the video, Bell shows step-by-step how the drone was built, from selecting motors and fine-tuning propellers for maximum performance to polishing the body to reduce drag. Luke Bell's father, Mike Bell, also shares his own insights into the process in the video below
