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.

How a Solid-State Process Stood Firm Until Additive’s Moment
Early on, this company saw the promise of friction stir welding for building forms in layers. Few understood at the time. They understand now, in part because this process offers benefits such as blended materials and freedom from stress that other metal AM approaches can’t match.
