Oak Ridge National Laboratory and Idaho National Laboratory have announced they will collaborate to help industry develop a process for wire arc 3D printing of industrial pressure vessels used for nuclear energy and chemical processing.

“By working with industry to demonstrate, validate, and qualify advanced manufacturing technologies, we can reduce risk, accelerate deployment, and strengthen the domestic supply chains essential to America’s energy future,” said Robert Wagner, ORNL associate laboratory director for energy science and technology.
