Yea I think the 3D printing thing is going to be huge!
But I don’t think it will be in the average home
anytime soon making replacement parts for your car.
But I can see these being used in just in time manufacturing big time (Automation anyone?).
Maybe even at local shops where you can order a quality part (quality materials) and pick it up in a few minutes/hours etc…
I just don’t think the quality will be there in the home market for quite some time yet, maybe never.
This was started in my home town BTW, (Go Valencia)
