A 3D printer at ORNL's Manufacturing Demonstration Facility was used to print an unusual crack-free alloy for use in turbines that operate at extreme temperatures.
Researchers at Oak Ridge National Laboratory and the National Energy Technology Laboratory have developed and 3D printed the lightest crack-free alloy capable of operating without melting at temperatures above 2,400 °F. This milestone could enable additively manufactured turbine blades to better handle extreme temperatures, reducing the carbon footprint of gas turbine engines such as those used in airplanes.
