Electron Beam Melting Manufacturing for DACS Divert Dome

CalRAM, Inc., a small-veteran owned company, has been developing a capability for producing near-net shape titanium components directly from CAD files. The process uses a layer-build or additive manufacturing process to build 3-D structures by melting titanium powder directly with an electron beam. The mechanical properties are comparable to conventionally fabricated Ti-6Al-4V. Working with Aerojet of Sacramento, CA, CalRAM proposes to demonstrate that electron beam melting manufacturing is a feasible process to produce the SM-3 Divert Dome at a reduced cost while simultaneously improving the production reliability. This will be accomplished by manufacturing the part in one piece eliminating all of the machining and joining presently used to manufacture the component.
