This paper presents a novel approach in the fabrication of rolled capacitors using a printable conductive ABS composite filament. On the contrary to conventional manufacturing of rolled capacitors, here a fused filament fabrication (FFF) technology, which allows a simpler and cheaper procedure of production is used. Also, a simple model of a 3D printed rolled capacitor is developed and the capacitance of the fabricated capacitor is calculated. The capacitance of the fabricated capacitor is measured in the frequency range from 100 Hz to 100 kHz. The measured capacitance is in good agreement with the calculated capacitance. It confirms the possibility of using conductive ABS composite filament for fabrication of 3D printed electrodes which could be formed passive device such as rolled capacitor or sensor for measuring liquid level.
