3D printing rocket engine parts

MTI produced components for NASA JSC out of Inconel 718 alloy. The material is robust enough to withstand extreme heat and corrosive environments without losing its rigidity or becoming brittle. "The project provided amazing collaboration between the NASA and MTI development teams and the results were excellent," said Gary Cosmer, Chief Executive Officer for MTI.

 

The joint collaboration yielded components that will withstand temperatures well above the melting point of the material. This, of course, would be impossible without engineered cooling. That's where 3D printing shines. Recirculating gases can be channeled throughout the component by invisible channels that are literally built into the component, one layer at a time.

 

has multiple business units working on projects as part of an effort to leverage best practices using digital manufacturing methods, including 3D metal printing.

 

Teams of propulsion engineers and scientists are working to integrate additive manufacturing methods such as conformal regenerative cooling channels or other geometry not constrained by traditional manufacturing techniques; all with a common goal of increasing performance and/or reducing weight. 

 

Additive manufacturing (3D printing) has a clear business case for space flight development. As such, MTI has embraced the technology and is now being called upon to produce components for the customers they have served with traditional manufacturing techniques for over thirty years.

 

Keeping in mind that the end game is to reduce cost and weight while increasing performance, these targets are important milestones for NASA as it reaches out further into space. MTI is no stranger to space related projects and has also produced forgings for the Orion capsule, which will travel upon NASA's Space Launch System designed for missions to Mars and beyond.
