Researchers are manufacturing steel and titanium aircraft parts using laser metal deposition technology. It can be used to 3D-print parts from scratch or to fix existing parts with a bond that is as strong as, or in some cases, stronger than the original.

The technology could completely transform the concept of warehousing and transporting for defense and other industries. Instead of waiting for spare parts to arrive from a warehouse, an effective solution will now be on-site.
