In this study, ABS-ZnFe2O4 composites were successfully fabricated using a 3D printer and the mechanical, thermal, and electrical properties of this material were investigated. This study examined the effect of the raster angle and filler content on the properties of ABS-ZnFe2O4 composites. The results showed that the raster angle had the least influence on the mechanical, thermal, and electrical properties of ABS. The highest reinforcing effect was when the ABS was loaded with 14 wt.% of ZnFe2O4 filler. The tensile strength increased by 52%, and the hardness increased by 75% compared with unreinforced ABS. Thermal conductivity improved 87% after 14 wt.% of ZnFe2O4 was added, while the electrical conductivity increased by one order of magnitude but remained in the insulative region. This result may be suitable for electrostatic discharge material application that requires good thermal conductivity but low electrical conductivity with good mechanical properties.
