Keystone is featuring Additive and Digital Direct Manufactured (DDM) parts made from titanium, nickel superalloys, steel, and aluminum alloys and has developed EB and robotic DDM methods to produce parts from a few pounds to over 600 pounds of deposited weight. Keystone makes parts for turbine engine and airframe applications, large non-critical components, reconstructive repair of components, and complex layup tools for composites. Keystone has developed Thermal Stir and Friction Stir Welding for titanium and nickel based alloys and recently produced the largest titanium FSW assembly for a ship deck. Keystone will have samples of AM and DDM parts and titanium FSW at booth 804.
