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.
