Dynamic mechanical properties of fused deposition modelling processed polyphenylsulfone material

Fused Deposition Modelling (FDM) has attained its reputation due to the capability of rapidly fabricating prototypes from concept design to real parts in shorter time and lower cost than traditional manufacturing processes. This study sheds light on the dynamic mechanical properties of Polyphenylsulfone (PPSF) material fabricated by FDM additive manufacturing process considering the effect of its various process parameters. Three major FDM process parameters are considered in this study, namely, raster angle, raster width and build style. Dynamic Mechanical Analysis is carried out with sweeping temperature at three different fixed frequencies, e.g., 1 Hz, 50 Hz and 100 Hz. Taguchi method is employed for the optimization of process parameters towards achieving better damping properties. Experimental results such as maximum storage modulus, maximum loss modulus, peak of Tan Delta and maximum complex viscosity are captured and the effects of process parameters on these damping properties of PPSF samples are investigated.
