GE Additive announced that GE Aviation made a significant investment in its electron-beam-melting (EBM) technology with the purchase of an additional 27 systems (17 Arcam A2X and 10 Spectra systems). Avio Aero, a GE Aviation company, currently operates a fleet of 35 Arcam machines at its recently expanded site in Cameri, Italy. The additional EBM systems will be installed at GE Aviation and Avio Aero facilities in the U.S. and Europe. They will be used primarily for the production of titanium aluminide (TiAl) blades on the low-pressure turbine for the GE9X engine.
Additively manufactured TiAl blades are roughly half the weight of traditional nickel-alloy turbine blades. GE Additive produce six blades per batch, while the Spectra H system can produce up to 10 blades in around the same time.
