Mechanical properties of copper ferrite CuFe<inf>2</inf>O<inf>4</inf>-polymer composite fabricated using 3D printer

The effect of speed of powder dispenser on the mechanical properties of ABS-CuFe2O4 composites was studied. The samples in the experiment were printed by a 3D printer which produces three-dimensional objects from the digital file which are built up layer by layer. The amount of filler content added into each sample was controlled by the speed of powder dispenser which is off, low, medium, and high. The properties of pure ABS and composite ABS CuFe2O4 samples were investigated based on the distribution of fillers. Weight percentage (wt%) of filler added into each sample was determined by using thermogravimetric analysis (TGA). Tensile test and Vickers micro hardness were carried out to determine the effect of filler content on mechanical properties. Addition of filler content in ABS matrix slightly decreases the strength of composite from 17.1 MPa to 14.64 MPa.
