Three-dimensional (3D) printing is regarded as a future-oriented additive manufacturing that is making significant contributions to the polymer processing field. Among the 3D printing methods, the DLP (Digital Light Processing) technology because it requires a short printing time and enables high-quality printing through selective photopolymerization of polymeric materials. In this study, we report a fabrication method for ABS-like resin composites containing polyaniline (PANI) nanofibers and graphene flakes suitable for DLP 3D Printing. As-prepared ABS-like resin composite inks employing PANI nanofibers and graphene flakes as co-fillers were successfully printed, obtaining highly conductive and mechanically robust products with the desired shapes and different sizes through DLP 3D printing. This study suggests the potential use of highly conductive and mechanically robust ABS-like resin composites in the 3D printing industry.
