Pratt & Whitney, a subsidiary of aerospace/protection large RTX, has developed a brand new methodology leveraging directed vitality deposition (DED) additive manufacturing (AM) to restore vital elements on its geared turbofan (GTF) engines. Pratt & Whitney claims that the DED upkeep, restore, and operations (MRO) method reduces restore time by over 60 p.c, in comparison with present strategies.
Based mostly in Connecticut, Pratt & Whitney developed the MRO course of at its North American Know-how Accelerator (NATA) in Jupiter, Florida, in collaboration with the non-profit Connecticut Heart for Superior Know-how (CCAT) and the RTX Analysis Heart. Pratt & Whitney introduced the opening of the NATA, its second expertise accelerator — following the opening of the Singapore Know-how Accelerator in 2022 — precisely a yr in the past.
In that authentic announcement, Pratt & Whitney referenced the challenge centered on AM restore for GTF engines as a central focus of the brand new facility with out specifying that DED was the tactic in query. The corporate is now planning on industrializing the method with a purpose to scale it throughout its international MRO community for the GTF engine, anticipating that it’ll allow the restoration of $100 million value of components over the following 5 years.
Within the press launch from April, 2024, in regards to the opening of the NATA in Florida, the VP of Aftermarket Operations at Pratt & Whitney, Kevin Kirkpatrick, stated, “NATA combines information science with folks know-how and state-of-the-art automation to assist tackle buyer ache factors equivalent to stock administration and half availability, whereas accelerating our improved restore capabilities and effectivity to higher serve our clients.”
In the meantime, in a press launch in regards to the preliminary success of the DED challenge for GTF MRO, Kirkpatrick stated, “[A more agile, additive repair process] reduces our dependency on present materials provide constraints. Additive expertise has the potential to assist a spread of vital GTF half repairs and we’re actively working to discover further alternatives for implementation.”

As I simply wrote about Axtra3D’s launch of its TrueSilX50 materials and enlargement of its reseller community, newcomers within the AM trade could find yourself being the largest winners of any acceleration to US reshoring that outcomes from the mounting uncertainty yielded by the Trump administration’s commerce warfare insurance policies. This goes for processes and applied sciences simply as a lot because it does for merchandise and firms, and DED — a relative newcomer in comparison with extra established processes like SLA, FFF, and PBF — is completely poised to reap the advantages of accelerated reshoring.
Past the symbolism of saying the success of the DED challenge precisely a yr after the NATA was introduced, it’s noteworthy that each the challenge and the mission of the NATA are working as deliberate, insofar as that trajectory bodes effectively for Pratt & Whitney’s long-term plans to scale up the DED course of and department out into different AM purposes. That’s precisely the kind of trajectory the AM trade must instill the required confidence {that a} scale-up of additive applied sciences is a viable technique as a complement and, finally, a substitute for present provide chains.
If the challenge continues to work out as deliberate, there may be vital potential to construct on it, provided that the price financial savings yielded would presumably be re-invested into additional R&D. Thus, Pratt & Whitney has not solely developed a brand new methodology for engine MRO however is establishing a mannequin for bringing the economics of AM into a brand new section of maturity.
