Cuts down on waste
The opportunity exists to
make more complex parts
within systems than ones
made using conventional
machining
Printed parts are up to 65%
lighter without
compromising strength
Engineers at EADS
It is simply easy to make
(the European Aeronautic Defense
things.
and Space Company) are researching
ways of using the technology to build
lighter, stronger parts for airplanes.

"The bottom line is that for the first time in
human history complexity is free -- making
something complicated takes the same
amount of time, resources and skill of making
something simple… This is a profound departure
from the past.“
Hod Lipson,
director of Cornell University's Creative
Machines Lab
