A3DM Precious Metal Powders include both Gold and Silver alloys used primarily in fine jewelry and luxury watch industries.

Traditional precious metal powders are processed by Inert Gas Atomization which yields a broad particle size range of "spheroidal" powders 

Inert Gas Atomized Powder
RF Plasma Powder  

A3DM reconditions and classifies gas atomized powders to remove adherent sub-micron particles, optimize flow characteristics, and refine particle size distribution

The result is a dense "spherical" powder with superior performance characteristics for precision Additive Manufacturing applications.

RF Plasma is a "Refractory Free" process where the potential of inclusions from ceramic melt crucibles is eliminated

The Low Turbulence process reforms inert gas atomized particles to a dense spherical morphology
