Using additive manufacturing to develop 
high pressure/high temperature combustion chambers 
and nozzles with copper alloys 
Technology Innovation Opportunities of the LCUSP Program 
• Address selective laser melting technology 
with copper and demonstrate the concept by 
designing, manufacturing and testing the 
critical components of a rocket engine. 
• Manufacture complex components rapidly 
• Demonstrate a hybrid processing process 
using selective laser melting (SLM) and 
Electron Beam Freeform Fabrication (EBF3) 
with NASA developed GRCop 
• Reduce cost and schedule if these 
challenges can be solved 
MSFC partnering with LaRC (for the EBF3 jackeUmanifold deposition) and GRC (for materials properties detennination)
