For as long as cars have existed, three fundamental truths appeared to be eternal. First, every car contains safety critical components, second these components are mostly metal and third, they are manufactured by one of two methods—stamping or cold forming.

It’s hard to think of a more trite and dependable set of principles. But these timeless precepts are about to become disrupted as the automotive industry continues to explore the innovation of 3D printing.
