I watched that video!
Do you think that people with normal means would ever buy 3d metal printers to keep their old cars on the road?
I broke two serpentine belt tensioners on Mom's Camry and the power steering pump on my Accord because you were supposed to put a great deal of torque on an aluminum part, so I have always wondered about marking part of that out of steel.
I cannot think of any metal parts that have failed on my car, but I could totally seeing someone making a stronger replacement.
Hey freebeard, I am glad you remembered my post!
It is too bad they failed. They did interesting work!
