Aeroship Components (e.g., GE LEAP Fuel Nozzle) Aeroship Components (e.g., GE LEAP Fuel Nozzle)GE Aviation’s 3D printed LEAP engine fuel nozzle is a landmark in aerospace engineering. Instead of assembling 20 separate parts, the nozzle is printed as a single piece using durable cobalt-chrome alloy, reducing weight by 25% and increasing durability fivefold. The complex internal geometry improves fuel efficiency and reduces emissions. Mass-produced using direct metal laser melting, over 100,000 nozzles have been made, proving metal 3D printing’s viability in large-scale industrial applications. This innovation reduces part count, enhances reliability, and accelerates engine development. It marks a shift in manufacturing, allowing for lighter, more efficient aircraft components and paving the way for broader adoption of additive manufacturing in aviation and space exploration.
