During a recent interview, Jeff Immelt, the CEO of General Electric (GE 0.51%), acknowledged that 3-D printing has some practical applications in the world of building jet engines. He wasn't talking about printing entire jet engines themselves, but 3-D printers could be used to print their biggest parts. The turbine blade for instance, which is made from some of the most expensive high-heat material on the planet could one day be printed by a 3-D printer. Additionally, adopting 3-D printing would cut down the time to design and develop an engine by half.

In this video, Fool.com contributor Steve Heller isolates one 3-D printing company that he believes would be most likely to benefit from a 3-D printed aviation revolution.
