Researchers at the University of Sheffield’s Additive Manufacturing Research Center (AMRC) have printed a 1.5m (4.9ft) wide drone in an attempt to research how the technology fares when building complex aerodynamic geometries.Weighing less than 2kg (4.4lbs) and composed of nine snap together pieces, the AMRC UAV was built using an FDM process without any support material. While Sheffield’s current drone revision is only a glider, future models will incorporate more advanced propulsion mechanisms
