Fusion -- Tungsten Rising (IMAGE) DOE/Oak Ridge National Laboratory Caption Using electron beam melting, ORNL researchers are building innovative tungsten fusion components with complex, unique geometries that can't be made through traditional manufacturing. The electron beam allows for better control of heat distribution as tungsten is 3D printed layer by layer.
