3D printing of ABS Nanocomposites. Comparison of processing and effects of multi-wall and single-wall carbon nanotubes on thermal, mechanical and electrical properties

• Multi-Wall and Single-Wall carbon nanotubes affect thermoelectrical behavior. Fuse Filament Fabrication of conductive nanocomposites at selected low resistivity. 3D manufactured with applications for thermoelectric devices/sensors. Anisotropy in electro-mechanical behaviour multilayer nanocomposites. Conductivity CNT composites depends on filler content, process geometry. The following paper reports a comparative study the effects two types nanotubes, namely multiwall (MWCNT) single-wall (SWCNT) nanotube, properties 3D-printed parts produced acrylonitrile-butadiene-styrene (ABS) various loadings 5-10 wt.%. Quasi-static tensile Vicat softening temperature were enhanced increasing content. highest enhancement was observed ABS/CNT 10 wt.% loading. ABS/SWCNT showed higher modulus, better creep stability temperature. However, strength samples is relatively lower than that ABS/MWCNT. In addition, exhibited anisotropic electrical behaviour, which has conductivity through-layer about 2-3 orders magnitude cross-layer. reached 25.2 S/m, 9.3 S/m ABS/MWCNT wt.%, respectively. results obtained, i.e. successful fuse filament fabrication consequent electromechanical properties, confirm these printable nanocomposite could be properly utilized production, application up to 90 °C, devices and/or resistors flexible circuits.
