Have a nephew who’s on the cutting edge of this, he say’s it’s still in it’s early development. Largest piece currently possible is 12x12 inch’s and that it’s not as strong as a forged or machined piece and the tolerances aren’t there....yet. However, the pace of development is stunning and it’s getting there quickly.
When it gets to the point of explosion-proof parts, the gun control movement is going to break out in hives. Hell, they’re doing that already!
