A new drone with a jet engine may be the most complex flying machine printed on a 3D printer. The drone, presented this month at the Dubai Airshow, nothing like the popular Chinese radio-controlled toys. It boasts three-meter wings and an aerodynamic design that gives it a futuristic look. The company that developed the drone, — Aurora Flight Sciences and Stratasys — says that more than 80% of the unmanned aerial vehicle was created using a 3D printer. The drone weighs only 15 kilograms and can fly at a speed of up to 241 kilometers per hour. «This is the biggest, fastest and most complex printed on a 3D printer unmanned aerial vehicle in the world,» said Dan Campbell, engineer Aurora Flight Sciences. The drone consists of several hollow parts, created through simulation by the method of layer-by-layer weld. At the same time, the individual parts of the UAV were printed using selective laser sintering. In this process small portions of a special powders are heated and sintered together, forming the required object. Drone Aurora shows how useful 3D printing in the creation of lightweight aircraft. In particular, such drones may optionally be printed directly on Board of warships and then to go on this mission. They can even be used for peaceful purposes, for example for monitoring agricultural land or exploring the archaeological sites. According to LiveScience
