GE Reports-This Electron Gun Builds Jet Engines
AUGUST 20, 2014
The method builds the blades from a titanium powder fused with a beam of electrons accelerated by a 3-kilowatt electron gun. The gun is 10 times more powerful than laser beams currently used for printing metal parts. Avio developed the technology, called electron beam melting or EBM , together with Sweden’s Arcam. The printer builds parts directly from a 3D computer drawing by melting layers of fine powder with an electron beam.
