Or, molds/plugs for intakes, oil pans,  radiator/oil cooler diffusers, 
etc. Ask Ed A. how much time it would have saved when casting his 
plastic intake manifolds if he'd been able to generate the molds from 
CAD files fed to a 3D printer. And it wouldn't surprise me if you can 
get 'feedstock' for one of these that would allow printing a usable  
intake or oil pan directly from the CAD file
