Absolutely, Ann. No doubt that a widening number of materials choices and improvements in strength, durability, and flexibility have fueled the use of 3D printing for a wide array of prototyping and small production runs.
It's especially interesting that this use of 3D printing for end-use components is happening in an automotive app. I think there's huge potential for 3D printing of end-use components in commercial car manufacturing. Also, the decision to design the car as a single unit might help current automakers figure out how to use multiple lightweighting materials in a single model.
