An Unmanned Aerial Vehicle (UAV) in Virgina University has been designed by contribution of MITRE coorperation, where the team has been working on the project for years. The team used a different technology for this robotic device and it is recorded as the third 3D-printed plane which can fly stable in the world.
This plane owever is quite expensive. $250,000 was spent for turbofan and about $2,000 was spent for 3D painting technology.
