Industry 4.0 offers the opportunity for manufacturers to optimize their operations quickly and efficiently by manipulating recent advanced technologies such as additive manufacturing using printing. An advance in the use of polymeric additive manufacturing has opened up wide possibilities for advanced based product manufacturing. With recent development of petrochemical industry, plastic products have made our society more convenient. However, the disposal of plastic based products has become a serious threat to the environment. This has contributed towards the environmental problem. Nanocomposite technology has been described as frontier of material science due to the employment of few amount of nano filler which significantly enhanced the resulted mechanical, thermal, physical and barrier properties. Therefore, this study is a preliminary effort to investigate the feasibility of creating recycled ABS/GNPs nanocomposites materials and determine their usability to be used as filament materials for 3D printer application. The r-ABS based nanocomposites were set at between of 0.00, 0.25, 075, 100, and 3.00 wt. % of GNPs nanomaterials addition. The samples properties of -ABS/GNPs nanocomposites that were prepared by using extrusion and hot press machine were studied. The mechanical, morphological, thermal and physical characterization were determined by using Universal Testing Machine (UTM) machine, Scanning Electron Microscopy (SEM) machine and Differential Scanning Calorimetry (DSC). The addition of GNPs as nanofiller in -ABS matrix was found not improving the resulted mechanical properties. Through SEM analysis, it was found that GNPs not compatible with r-ABS and create major phase separation between the r-ABS matrix and GNPs nanofiller. Thermal stability of composites indicates that the glass transition temperature was largely unchanged as a result of GNPs addition. Although the r-ABS/GNPs nanocomposites did not shows any increased of mechanical strength that were hypothesized to occur, large increased in material stiffness could still be contributed for 3D printed parts where these stiffness characteristic could served as reinforcing material to traditional ABS or other printed type materials. In overall by conducting this study, it can be said that the utilization of r-ABS as recycled polymer was not compatible for incorporation with GNPs nanofiller. For future improvement, it can be suggested that the GNPs nanofiller used could be surface treated or modified beforehand, prior of the mixing with polymer phases. Hence, there are still hopes for this research work in improving the properties of r-ABS by adding the nanofiller for 3D printing usage.
