RE: 3D Printing Tank Treads, etc
I looked at one of the links, but are these all printers that use various forms of plastics?
I was listening to a story on the radio just the other day, and the guy made the comment that anything that can be made into a powder, theoretically the proper 3D printer would be able to make the product out of.
Can only hope that means that powdered aluminum and steel 3D printers are coming (or are already out there) at a price many can afford.
