Fused Filament Fabrication (FFF) has been widely used for the Additive Manufacturing of polymer-based components. Due to the versatility of equipment used in FFF, the feasibility to incorporate other classes of materials within the polymer filament, such as metallic and ceramic powders, is an attractive option. When metallic powders are incorporated into the polymer, FFF provides the opportunity to retain the fine structure of the rapidly solidified powder. This work will discuss the random loose porosity for mixtures of metal matrix composite (MMC) powders containing Nickel alloy, Titanium and Tungsten carbides. The packing of fine and non-spherical particles for these powder mixtures will provide a datum for determining the maximum packing achievable to increase carbide content, and for predicting the flow characteristics of composite filaments containing polymer and MMC fillers for use in FFF. The printability of the composite filaments in relation to particle packing will also be discussed.
