Before we even begin, let me tell you that the answer is 3D printing. Yep, that thing can make aircraft engines and working cars. Meet the Urbee hybrid, the car whose entire body has been created with 3D printing. All external components on the car have been 3D printed, and it isn’t just some display model either. Developed by Stratasys and Kor Ecologic, Urbee can run on ethanol or gasoline, it gets 200mpg on the highway, and can get nearly 100mpg in city conditions.
