Injection molding dominates the polymer converting and remains the best technique for high volume production. Nowadays, 3D printing has begun to gain attraction by offering an alternative at costs competitive with injection molding for low-volume runs. Nanocyl as carbon nanotubes manufacturer and specialty compounder provides high quality thermoplastic masterbatch for injection molding processing where electrostatic dissipative and conductive properties are required. Those properties were proven also essential for 3D printed component. In this approach, Nanocyl developed new thermoplastics compounds dedicated for Fused Deposition Modeling FDM technology. In this paper, we report the development of carbon nanotubes dispersion in ABS thermoplastic by melt blending. Characterization of CNT dispersion state was done at compounds stage by mean of optical microscopy. Compounds with different concentration of CNTs were extruded to fabricate filament with 1.75mm of diameter followed by 3D printing. Electrical conductivity were carried out both for filament and 3D printing component. It was shown that ESD properties for printed part was achieved for lower concentration of CNTs.
