Manufacturing “Living Metals” With Cold-Spray Technology Is Rocket Science

The promise of metal additive manufacturing hasn’t quite matched its initial hype. Costs are still high, and the tech remains best suited to fabricating low-volume, high-complexity parts. In short, it hasn’t been the anticipated boon to industrial manufacturing yet—so using a rocket engine to spray and bond metal particles onto existing machine parts might seem a little like overkill.

A Bay Area trio with a unique start-up idea may be changing all that. Co-founder engineers Deepak Atyam, Alex Finch, and Jesse Lang of Tri-D Dynamics have developed what they call “cold metal fusion,” which combines powder-based metallurgy with rocket science—and perhaps will open an untapped market in the process.
