Abstract Scope |
Manufacturing polymer-metal composite products of desired quality using fused filament fabrication (FFF) technologies requires a comprehensive understanding of the material and the process. There has been a substantial effort in recent years on modeling polymer FFF, however, polymer-metal composites exhibit unique physical behaviors. These unique conditions, such as particle-fluid interactions and visco-elastic effects on melt flow, complicate simulation dynamics rendering existing modeling methods ineffective in predicting the melt behavior. This work leverages a computational fluid dynamics modeling approach to simulate the deposition of a homogeneous polymer-metal composite in the FFF process. This approach allows for an efficient investigation of the effects of the process parameters, such as nozzle temperature, nozzle speed, and material composition, on the application-relevant quality of the deposited material. Quantities of interest such as the profile of the deposition and the thermal history are studied. Future considerations for a heterogeneous simulation are also discussed. |
