Abstract Scope |
Utilizing the Fused Filament Fabrication (FFF) additive manufacturing process with feedstock comprised of metal particles in a polymer binder is a relatively new technique for fabricating metal parts. This study investigated several bound-metal filament feedstocks, one incorporated 4140 steel powder, another incorporated 6061 aluminum alloy powder, and others incorporated novel Fe-Mn alloy compositions. The ability to use Fe-Mn alloy compositions in FFF is of interest due to their ability to manipulate shock waves through their phase-transforming properties. FFF process parameters were developed to facilitate fabrication of suitable specimens. After fabrication the samples were consolidated using debinding and sintering techniques. Processing-Microstructure-Mechanical property relationships were investigated and optimized in order to reduce defects and obtain the best mechanical properties in the samples after sintering. The ability to fabricate novel lattice structures using bound-metal FFF technology was also investigated. |
