Amazing machines poised to fly travelers into a new era
The laser melts fine metal powder into a precisely shaped solid metal layer so thin that it’s one-third the diameter of a human hair. When it’s done, the result is an extremely precise, complicated jet fuel nozzle — no assembly required. The old way of making nozzles required welding together about 25 separate parts.
GE engineers said it represents the first time additive manufacturing has been used to create a jet engine component tasked with such an important role under high temperature conditions.
