Once finished, the plane was able to travel as fast as 100 mph and could even fly itself, thanks to an autopilot module. The plane's wing was modeled after that of the the legendary Spitfire plane, whose elliptical wing is considered too difficult and expensive to make using standard techniques. But using the laser sintering method, it became much easier. Ultimately, it would be amazing to see this new way of designing aircraft lead to breakthroughs in larger planes that people actually fly in.
