Unreal intake manifold cost

At this point I'm just gonna wait for metal 3D printing technology to get to the point where we don't need castings anymore. It's pretty close maybe 2-4 years out? The tech is there it's just still a bit too expensive for the common man. And intake manifolds would be easy because they don't have moving parts and aren't under much stress. People are already 3D-printing custom plastic intake manifolds for EFI applications.
