Extensive work has been carried out regarding the usage of solid fillers to make composites in an Additive Manufacturing (AM) process, but little research has been done with respect to incorporation of immiscible liquids in the process. Fused Deposition Modeling (FDM) or Fused Filament Fabrication (FFF) is an AM process in which a solid thermoplastic filament such as Acryolonitrile Butadiene Styrene (ABS) or Poly Lactic Acid (PLA) is melted and extruded through a nozzle. In this study we inject an additional fluid radially through the side of a custom-built conical nozzle, as the melted filament flows along the negative z-axis. This work will be in the first step in understanding the behavior of liquid fillers in a polymer flow and will also help in incorporating liquids in polymer based additive manufacturing on a much bigger scale. The nature of the fluid deformation is also studied to control and model the printing process.
