Three Cool Uses for Directed Energy Deposition
Most machining professionals don’t like to admit that they ever make mistakes, but every now and then wouldn’t it be nice to have an “eraser” to go back and repair a gouge or fix a nicked edge? Or maybe you took off a bit too much material on that last machining pass and you’d like to add it back? Well, directed energy deposition (DED) enables you to do that and more.
