Throughout the process of building between the two additive 
manufacturing methods. material characterization and analysis 
helps develop relationships between build parameters, 
microstructure, and mechanical porfom1once that can be used 
to Inform future manufacturing and design decisions. Nil GRCop-84 and IN~25 mechanical properties 
Hot Fire Test in relevant environments demonstrates 
the technologies and advances Technology and 
Manufacturing Readiness Leve.ls of the copper alloy 
additive manufacturing process, the Electron Beam 
Free Form Fabrication process and the combination 
of both for rocket engine components.
