General Electric made roar its first 3D printed turbojet engine

General-ElectricInspired by a mini reactor model, unveiled by the Additive Development Center of General Electric engine propel never a real plane. It nevertheless marks a step in the industrial history of the American giant. All parts of this mini Turbo was produced by 3D metal printing and the engine is fully functional. Equipped with sensors and connected to a fuel system, the engine was able to turn to the bench. 33,000 rpm, just like the big engines produced by General Electric.

Beyond demonstrations, 3D printing arrives in series engines

It is a little response from General Electric to Amaero Engineering and the french Microturbo/Turbomeca, of Saffron that had unveiled a Jet engine during the Airshow of Avalon subsidiary. GE-mini-réacteurThe franco / Australian unveiled their «turbojet 3D» the first, but GE grid them politeness by turning his first. The simpler it is true, was entirely produced with a 3D metal type Eos M 270 printer. A type MSLD (Direct Metal Laser-Sintering) printer that melts the metal by laser micro to produce, layer after layer the desired room. This printer is capable of producing parts of titanium, Inconel, aluminium. General Electric did not specify what alloys were used for its reactor, but parts were due to be machined, especially polished before be mounted.
Beyond these demonstrations, 3D printing enters the series turbojet. General Electric produces parts in 3D printing for the all new engine LEAP but also to modernize the 400 already produced GE90 engines mounted on the Boeing 777.
The manufacturer hopes to produce 100,000 by 2020 3D printing parts.
