Pratt & Whitney says it will deliver jet engine parts produced using additive manufacturing, also known as 3D printing.

The company says it will be among the first to use additive manufacturing to make compressor stators and synch ring brackets for its PurePower PW1500G engines, which power the Bombardier CSeries aircraft. the company says it has made more than 100,000 prototype parts over the past 25 years using additive manufacturing techniques.

"Additive manufacturing offers significant benefits to the production of jet engines," says Lynn Gambill, chief engineer, Manufacturing Engineering and Global Services.

During production tests, the company says it has accomplished up to 15-month lead-time savings compared to traditional manufacturing techniques, and also reduced the total weight by up to 50%.

Related manufacturing technologies that will be used in the PurePower engine production include metal injection molding, electron beam melt and laser powder bed fusion (including direct metal laser sintering).

The company also plans to invest in further research in 3D printing; the Pratt & Whitney Additive Manufacturing Innovation Center has more than $4.5 million invested and provides educational opportunities for manufacturing engineers.

"We are a vertically integrated additive manufacturing producer with our own metal powder source and the printers necessary to create parts using this innovative technology," says Tom Prete, Pratt & Whitney's Engineering vice president. “As a technology leader, we are intrigued by the potential of additive manufacturing to support our suite of technologies and benefits to customers and the global aerospace industry."
