AUBURN, Alabama — GE Aviation’s plant in Auburn achieved a milestone this week — the 30,000th additively-manufactured fuel nozzle tip “grew” on a 3D printer at the facility, the industry’s first site for mass production using the additive manufacturing process.

Employees at GE Aviation in Auburn began producing the nozzle tip in 2015. More 3D printers have been added since the facility started additive production, and now, more than 40 printers are making parts from a metal powder. “This milestone isn’t just about reaching production of 30,000 fuel nozzle tips. The team should also be proud for their role in helping prove additive technology works in mass production for our business and others who buy GE technology,” said Ricardo Acevedo, plant leader for GE Aviation Auburn. GE announced plans in 2014 to invest $50 million in the existing 300,000-square-foot Auburn facility to prepare the building for the additional additive work. There are 230 employees at the plant, with projections for employment at the advanced manufacturing location to increase in 2019 to 300 staff members.

‘LEADING THE WAY’

Unlike traditional manufacturing methods that mill or cut away from a slab of metal to produce a part, additive manufacturing (also referred to as 3D printing) grows parts directly from a CAD file using layers of fine metal powder and an electron beam or laser. The result is complex, fully dense parts without the waste, manufactured in a fraction of the time it would take using traditional methods.

Under the additive manufacturing method, the number of parts in a single fuel nozzle tip was reduced from about 20 pieces previously welded together to one whole piece. The nozzle tip’s weight was cut by about 25 percent.

“We’re leading the way of mass producing additive parts for the industry. We’re continuously looking at ways of expanding the possibilities for the business,” Acevedo said.

GE Aviation started making additively-produced fuel nozzle tips for the LEAP engine, commercial aviation’s best-selling engine with fuel efficiency up to 15 percent better than the best CFM56 engines.

Total LEAP engine orders and commitments currently exceeds 16,300 engines.

LEAP engines are a product of CFM International, a 50/50 joint venture company between GE and Safran Aircraft Engines and the world’s leading supplier of commercial aircraft engines.

UNIQUE MATERIALS

The Auburn facility in not GE Aviation’s only cutting-edge manufacturing operation in Alabama.

Earlier this year, the company opened a new $200 million factory complex in Huntsville that will be America’s first production center for unique materials used to manufacture ceramic matrix composites (CMCs).

Les CMC sont prêts à révolutionner la fabrication aérospatiale en raison de leurs propriétés ultralégères et de leur capacité à résister à des températures extrêmement élevées.
