Our proprietary directional recrystallization (DRX) technology gives printed superalloys the high-temperature strength to survive the hottest, highest-stress section of a gas turbine engine.
See the technologyAdditive manufacturing can already build engines that are lighter, more efficient and easier to produce — but not the parts that survive inside them. A critical materials challenge has kept 3D-printed components out of the hottest, highest-value sections of turbine engines.
Top Grain is the enabling technology that closes that gap.
Top Grain is a high-margin, specialized technology provider — not a printer manufacturer. OEMs print; we make it engine-ready.
OEMs and their suppliers print raw superalloy components.
Parts ship to Top Grain, where DRX restructures the metal's underlying grain properties under aerospace-grade quality assurance.
We return high-stress components certified to withstand real turbine operating environments.

Top Grain has moved past the lab.These are paid, active programs — not pilot studies.
They power all jet air transport and roughly 40% of US electricity generation. Airplane build rates are rising, along with AI-driven datacenter power demand. SpaceX, GE Aerospace, Pratt & Whitney, Siemens Energy and other OEMs already rely on additive manufacturing for advanced engine hardware. DRX lets them use those parts in the engine section that matters most.
Funded by industry leaders to solve immediate, mission-critical supply and performance bottlenecks.
Patent-protected DRX, exclusively licensed from a premier research university and advanced under a federal defense program.
Flexible, domestic production across aerospace, power generation, oil & gas and defense.
The objective is not simply to print metal.It is to turn advanced high-temperature materials into reliable turbine engine hardware.
Top Grain Technologies is an industrial technology company developing and commercializing advanced materials and manufacturing technologies for critical gas-turbine components.
Metal additive manufacturing can produce sophisticated turbine-blade geometries, but the fine grain structures created during printing can limit creep strength under prolonged heat and stress.
DRX is being developed to transform that microstructure into larger, directionally oriented grains and improve high-temperature creep performance.
On the path to a production-qualified turbine-blade process. Component qualification, engine testing and production adoption are pending milestones.
We start with the material and service requirements of the engine part, apply design-for-additive-manufacturing expertise, and manage the full route:
For selected legacy components the value is simple: high quality, shorter lead time, and availability where the original supply chain may no longer serve the customer.
