Innovative design can be practical yet beautiful and uplifting. Sometimes it can literally take off. That is the case with some of the parts in the new GE jet engine, LEAP, set to start its commercial flights in 2016 in Airbus and other commercial airplanes. The design process of this engine is also the story of industrial use of 3D printed metal parts as exemplified by GE. If you want more information, metal 3D printing is part of a Master Class coming up during Dutch Design Week, for those planning to attend this event.
