additive manufacturing technical

"successful completion of demonstration testing for its additively manufactured TJ150 engine"

Additive manufacturing, often called 3D printing, builds physical parts by laying down material layer by layer from a digital design, rather than cutting or molding from a solid block. It matters to investors because it can cut production time and waste, enable cheaper prototypes and customized products, and reshape supply chains—changes that can lower costs, speed new products to market, and create competitive advantages that affect a company's revenue and margins.

expendable engines technical

"For expendable engines like the TJ150, where missions can last minutes or hours"

Rocket engines designed to be used once and discarded after a launch, rather than recovered and reused. Like disposable cookware compared with a reusable pot, expendable engines simplify design and lower up-front complexity but create recurring manufacturing and supply needs. Investors care because a company’s use of expendable versus reusable engines affects production costs, margins, capital spending, launch cadence, and long-term competitiveness in the launch services market.

rotating turbine wheel technical

"successfully tested a 3D-printed rotating turbine wheel"

A rotating turbine wheel is the spinning component inside a turbine that converts the flow of a fluid—like steam, gas, water, or air—into mechanical shaft power. Think of it like the blades of a windmill or waterwheel: its design, materials and balance determine how efficiently and reliably a plant or engine produces output, which affects production levels, operating costs, maintenance needs and capital spending that investors watch.

Additive manufacturing increases production speed and industrial flexibility to meet growing demand for expendable engines

LONDON, July 20, 2026 /PRNewswire/ -- Farnborough International Airshow – Pratt & Whitney, an RTX (NYSE: RTX) business, announced the successful completion of demonstration testing for its additively manufactured TJ150 engine.

Nearly 60% of the engine by volume was produced through additive manufacturing, including major static and rotating hardware. The testing focused on validating material behavior in an operational environment and demonstrating durability aligned with mission demands.

"For expendable engines like the TJ150, where missions can last minutes or hours, simplifying the design and scaling production quickly is essential to meeting rising demand," said Jill Albertelli, president of Military Engines at Pratt & Whitney. "Additive manufacturing helps us move designs from concept to capability faster, and we are leveraging what we learned on the TJ150 to benefit other programs, including the Pratt & Whitney Valox™ engine family."  

Pratt & Whitney has made targeted investments to advance additive manufacturing for the TJ150, strengthening its long-term producibility and scalability strategy. To date, Pratt & Whitney has consolidated more than 50 individual hot section components into a handful of additively manufactured parts and has successfully tested a 3D-printed rotating turbine wheel. Together, these efforts led to the recently tested TJ150 configuration.
