The world's fastest drone is 3D printed

What can you achieve by combining DIY engineering, manufacturing, and a clear goal? A fully 3D-printed drone that has 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 custom quadcopter, the Peregreen V4, to its limits to retake the speed record held by a rival team. This project stands out for its accessibility. Instead of relying on specialized industrial equipment, the Peregreen V4's body is printed as a single piece using a consumer-grade Bambu Lab H2D 3D printer, combining several materials to find the right balance between strength and aerodynamic performance. The result? The drone achieved a verified average speed of about 657 km/h (408 mph) over two runs in opposite directions—a figure that not only allowed it to reclaim the Guinness World Record but also shows how far small-scale, open-platform engineering has come… in both speed and ambition. Throughout the video, Bell walks viewers through the design steps: from choosing brushless motors and adjusting propellers to optimize high-speed performance, to polishing the shell to reduce drag
