Abstract

In this study, various nano and
micro particles with different properties, including density, surface area,
purity and particle morphology were used as reinforcement particles for the
production of polymer composite filaments to be used for 3D printing.
Acrylonitrile Butadiene Styrene (ABS) was matrix material and Multi wall carbon
nanotubes (MWCNTs), SiO2, ZrB2, and, Al particles were reinforcements.
Production of the composite filaments was carried out by using a twin screw
extruder. Produced composite filaments were characterized via Differential Scanning
Calorimeter (DSC), Scanning Electron Microscope (SEM), Energy-Dispersive X-ray
Spectroscopy (EDS), tensile test and surface roughness tests. Results showed
that addition of micro/nano particles into ABS matrix improved the Ultimate
Tensile Strength (UTS) of the composites by around 16% compared to
non-reinforced one. As a result of reinforcing with micro particles, ZrB2 and
Al, the tensile strain of neat-ABS filament increased by 17.8% and 40%,
respectively
