Abstract
Abstract Multiwall carbon nanotubes (MWCNTs) can be spread out in acrylonitrile butadiene styrene (ABS) using a twin‐screw micro‐compounding extruder. It can significantly improve the mechanical properties of 3D‐printed objects. Dispersed MWCNTs in pure ABS to develop the nanocomposites through a two‐time micro compounding extruding process. 3D printed filaments with a diameter of 1.75 mm have been prepared by processing the acquired composite structure through a filament extruder. The mechanical and other properties of 3D printed pure ABS and 1, 2, and 3 wt.% of the fused deposition modeling (FDM) process were studied for MWCNTs/ABS composites. Compared with pure ABS, the tensile and thermal properties were significant for 1, 2, and 3 wt.% of MWCNTs/ABS composites. Fourier transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM) were also analyzed for 0, 1, 2, and 3 wt.% MWCNTs/ABS composites. Additive manufacturing (AM) processes have recently been emphasized for their applications in electronics, aerospace, biomedical, and automobile engineering.
