Additive Manufacturing

  • Oct. 17, 2014 - NASA and Aerojet Rocketdyne successfully hot-fire tests an advanced additive manufactured rocket engine: Injector/Thrust Chamber Assembly.

Industry leader in 3-d printing, and material and design solutions

Aerojet Rocketdyne has invested extensive time and resources for more than two decades to evolve additive manufacturing technology, also known as 3-D printing, to meet the stringent requirements of rocket engine and defense systems applications. This investment is now paying dividends as we begin to incorporate the technology into production programs. 3-D printing can significantly reduce lead times, make products more affordable, and enable new approaches to design that were not previously feasible. In particular, 3-D printing has made a large impact on Aerojet Rocketdyne's ability to deliver hypersonic flight.

We are proud to have added 3D Material Technologies to our company in 2019. For more information, you can also visit

Key Features

Cost savings: The use of additive manufacturing dramatically reduces the amount of touch labor required to build many engine components, which enables us to provide more affordable products to our customers.

Design flexibility: Aerojet Rocketdyne’s engineering team has refined its approach to the design process to incorporate new capabilities enabled by additive manufacturing.  Engineers are free to design products that were once thought impossible due to the constraints of traditional manufacturing.

Shortened manufacturing timelines: Components that once took hundreds of hours to produce with traditional manufacturing techniques can now be built in just days using a single machine. This reduces lead times significantly and allows us to bring our products to market more quickly.

Our Role

Aerojet Rocketdyne is applying additive manufacturing to the following products: AR1, RL10, RS-25, Bantam Family, MPS-120 CubeSat, NASA’s Orion Crew Module propulsion components, and various missile defense and tactical products.
