It doesn’t look like they printed the rotors. It’s hard to find real concrete info but it looks like they added cavities to other parts of the engine for active cooling and/or increased strength to weight, which is more of a well explored topic (I remember watching a rocket engine test in Mojave with a hollow cryocooled aluminum nozzle in the late 2000s). The rotors are still made using those fancy 5-axis CNCs - I think either Boeing or GE still have a shop in LA that makes them. |
