The world's fastest drone was 3D printed

What can be achieved by combining DIY engineering and manufacturing with a clearly defined goal? A fully 3D-printed drone that has just reclaimed the title of the world's fastest quadcopter. The following video features South African engineer and YouTuber Luke Maximo Bell and his father testing the capabilities of their hand-built Peregreen V4 quadcopter in an attempt to take the speed record back from a rival team. What sets this project apart is its accessibility. Instead of relying on specialized industrial tools, the Peregreen V4's frame is printed in one piece using a consumer-available Bambu Lab H2D 3D printer, combining different materials to balance strength and aerodynamics. The result? The drone achieved a verified average speed of about 657 km/h (408 mph) during two runs in opposite directions—a feat that not only reclaimed the Guinness World Record but also shows how far (and fast) small-scale, open-platform engineering has come. In the video, Bell walks viewers through the design process: from selecting the right brushless motors and propellers for peak performance to polishing the frame to reduce drag
