Abstract: This study outlines the three dimensional (3D) printing of functional prototypes as electrochemical energy storage devices (EESD). The EESD has been prepared with acrylonitrile butadiene styrene (ABS)-graphene (Gr) blended feedstock filament on commercial fused deposition modelling (FDM) setup. The rheological suitability of ABS-graphene composite material for FDM applications has been examined by melt flow index (MFI) test. Finally the feedstock filament for FDM has been prepared on twin screw extrusion. The in-house prepared feedstock filament can be used for the 3D printing of EESD. The effect on glass transition temperature with the inclusion of Gr particles has been examined by differential scanning calorimeter (DSC) analysis. Moreover, Fourier transform infrared spectroscopy (FTIR) spectra visualised the structural changes in Gr/ABS matrix. Further, the study has been supported with scanning electron microscopy (SEM)-based photomicrographs.

Keywords: fused deposition modelling; FDM; electrochemical energy storage devices; EESD; FT-IR spectra; differential scanning calorimeter; DSC.
