Abstract
The current work investigates the compressive behavior of three-dimensional (3D) printed functionalized MWCNTs (multi-walled carbon nanotubes)/HDPE (high-density polyethylene) nanocomposite (NC) samples. The NCs are prepared by varying functionalized MWCNTs in the proportion of 0.5–5 wt. (weight) % in HDPE through compounding. The NC pellets are further used for extruding feedstock filaments to be used in fused filament fabrication based 3D printer. The crystallinity of NC filaments and prints is higher than HDPE filaments and prints respectively. The compressive modulus, yield strength, and the peak stress of the prints are observed to be increasing, whereas the energy absorption is observed to be decreasing with functionalized MWCNTs loading.
