Abstract : Acrylonitrile butadiene styrene (ABS) is a petroleum-based thermoplastic primarily used in fused deposition modeling (FDM) based 3D printing and injection molding applications because of its low cost and recyclability. The addition of carbon black (CB) makes ABS conductive and can be used in electronic applications. In this experimental work, the electromagnetic interference (EMI) shielding performance of 3D printed ABS-CB composite with varying thickness (0.2–2 mm) is investigated in the frequency range of 1 GHz–12 GHz and maximum shielding effectiveness (SE) is obtained for 2 mm absorber thickness at 2.4 GHz (S-band). Also, the composite has been characterized for its electrical and mechanical properties. The electrical conductivity increases with the inclusion of CB. But, the mechanical properties such as tensile and impact strength reduced with a rise in the CB content.
