3D printed parts created by GE have been incorporated into production of a large power plant in Germany, at the Berlin-Mitte facility. Currently the plant is using using 3D printed first-stage heat shields and first-stage vanes inside a single GE natural gas turbine. With 3D printing, more complex geometries can be achieved, as well as allowing for much improved efficiency. Read more at 3DPrint.com: https://3dprint.com/159881/power-plant-germany-ge-3dp/
