Mechanical Properties of Graphite Filled ABS Parts Developed by Fused Deposition Modelling

The current work focuses on synthesis of graphite filled ABS plastic filament suitable for Fused Deposition Modelling applications. The Effect of graphite reinforcement on mechanical properties of Acrylonitrile Butadiene Styrene (ABS) parts developed by FDM process have been studied. Twin screw extrusion technique was adopted for synthesis of filament required for FDM process. Pure ABS and graphite filled FDM parts have been subjected to microstructure and tensile studies. Microstructure studies confirms that graphite filled filaments are free from micro porosity. Tensile test shows that graphite filled ABS parts have exhibited significant enhancement in ultimate tensile strength when compared pure ABS parts.
