Boom, the YC backed supersonic plane lot are trying to make their own blades/engines to cash in on the AI rush which should be interesting.

They are a bit vague on how they are doing it:

>Q: What engine parts are you printing for Symphony?...High-Pressure Turbine (HPT) Blades: These blades spin at extremely high speeds, extracting energy from the hot gases

>While these additively-manufactured components won’t fly on the final Symphony engine, they are fully operational and critical to validating the core architecture. On Symphony, these parts will be replaced by ones made from more traditional manufacturing methods.

So I guess 3D printing the prototype? Dunno if they are going to make their own wax casting plant like in the Veritasium video? https://boomsupersonic.com/flyby/turning-powder-into-power-h...
