| Abstract Scope |
Fused filament fabrication (FFF) technology, an additive manufacturing process traditionally used for building plastic objects, has been commercialized for making metal parts. Metal FFF uses metal powder filled plastic filaments, coupled with debinding and sintering operations, and can produce molds for plastic injection molding machines. Such molds would greatly benefit from the introduction of conformal cooling channels as well as an enhanced thermal conductivity of material they are made of, traditionally steel. Presented research is focused on development of such a material – a bi-metal composite of steel and copper - that was shaped into a mold with conformal cooling channels via application of the metal FFF process. The bi-metal composite exhibited thermal conductivity of 108 W/mK and 110 GPa modulus of elasticity in an as-manufactured condition. Results for processing, microstructure and thermal and mechanical properties of the new bi-metal composite material will be discussed in the presentation. |
