The aim of this study is the development of the ABS-CuZnFe2O4 composites using 3D printer. In this study, the effect of filler loading on the mechanical properties and thermal conductivity is examined. The result shows that at highest filler loading (14 wt%) the tensile strength was improved approximately 98% while the Young’s modulus increased about 23% compared to unfilled specimen. Meanwhile, the percentage of elongation decrease approximately about 49% when filled with 14 wt% of filler. The CuZnFe2O4 filler shows a greater effect on hardness value of the composites around 498% at maximum filler content. The thermal conductivity of the ABS increased up to 60% at full capacity of filler.
