Keystone specializes in large-scale Additive Manufactured (AM) parts made from titanium, nickel superalloys, steel, and aluminum alloys and has developed low-cost robotic AM systems and methods to produce parts from a few pounds to over 600 pounds of deposited weight. Keystone has developed add-on closed-loop process controls for build height control, thermal management control, and in-process monitoring of melt pool characteristics. Keystone is actively producing hardware and tooling for large non-critical components for rocket and gas turbine propulsion systems, vessels, ground vehicles, and tooling. Keystone also performs 3-D printing of thermoplastics for prototypes and one-off parts. Visit Keystone at Booth 729 to see samples of AM parts and materials.
