This really has some revolutionary potential, and it might even benefit US manufacturing.
For example, instead of buidling vehicles centrally and shipping them all over the world, they could be built locally and assembled on site.
Likewise, spare parts inventories could be drastically reduced and replaced with raw materials and the sintering machine.
Engineering revisions to parts would take effect immediately, and so would all spare parts created after the change.
Plus, a given factory could be switched to a different line or even product type quickly.
Conceptually, you could have major manufacturers who specialize in simply building/assembly, contracting to whatever design company needed the service. The same plant could produce vehicles, aerospace, whatever or produce spares for a variety of industries.
Granted, that’s only for components that lend themselves to these processes, but I’d guess there’s quite a bit.
This may be the first class of machines that will be developed specifically to clone themselves. Large 3D machines in large numbers equals a revolution in manufacturing.
Big Investment is going to go into this field. Some will win and some will lose but the end result will, without a doubt, have a huge impact on US manufacturing. A revolution for sure.
