Key phrase is "..considers 3D printing..." Who knows what they'll end up doing. I thought they were going with carbon fiber composite fan blades, and ceramic matrix composite material for the LPT and case:

"As detailed by GE, the GE9X has a 133-inch diameter composite fan case and 16 composite fan blades; a 27:1 pressure ratio 11-stage high pressure compressor; a TAPS (twin annular pre-swirl) combustor for greater efficiency and low emissions; and ceramic matrix composite material for the combustor and turbine, as well as the blades."
