It was kind of a joke. Just be cool someday to just order up a cylinder head and have it 3D printed down the road so you didn't have to cast and then ship it. :D
I thought that might be the case, but technology changes so fast, it seemed like a good opportunity to share whats available these days.
I've been trying to get access to the renishaws for exactly that kind of thing, a 3d printed intake. It would have to be in multiple pieces and welded, no luck so far. Cost to operate is too high
