3D printing tungsten » The Unwanted Blog
Interesting comment about using 3D printing to create specialty engineered alloys, specifically silver impregnated tungsten for better heat conductivity internally to avoid localized melting on tungsten rocket nozzle throats. In this application, it wouldn't be a conventional casted alloy, nor would it be a gradient mixed/poured alloy either, but perhaps a design specific 3D spacial gradient? Or would you be doing the design equivalent of embedding a heat pipe of sorts in the tungsten for short range directed heat transfer?
