The idea of Rolls Royce, which plans to use 3D-printing technology in the manufacture of individual parts of jet engines, was picked up by its equally well-known competitor - the American General Electric (GE). As you know, the essence of this technology is to create a specific physical object layer by layer using a special 3D printer.
GE intends to use this method to manufacture over 85, 000 fuel injectors for its novelty, the Leap jet engines. So far, these are only plans, but it seems that the decision on their implementation has already been made, and the necessary funds will be allocated in the near future.
What does it do? A conventional fuel injector consists of two dozen parts, which are manufactured at several subsidiary enterprises. 3D printing technology will make it possible to produce finished products in one place, which will make them much more reliable and cheaper by reducing time and production costs. Such injectors, located inside a jet engine, will be able to withstand temperatures up to 1315 ° C.
Many experts believe that the introduction of such technologies over time should affect the reduction in the cost of air tickets, a significant part of which is accounted for by fuel.
