Berlin’s Mitte Power Plant Used 3D-Printed First Stage Heat Shields

The Berlin Mitte plant, operated by the power company Vattenfall, is using 3D-printed first-stage heat shields and first-stage vanes inside a single GE natural gas turbine. Each part weighs about 4.5 kilograms (9 pounds) and is the size of a laptop. “These are the largest 3D-printed components globally in any commercially operated gas turbine,” says Wolfgang Muller, product line leader of GE Power Services’ gas turbine e-fleet. “3D printing is often thought of in terms of very small, complex components. We’re proving now that actually, you can commercially manufacture large pieces for turbines.”
