Preliminary investigation of acrylonitrile butadiene styrene (ABS) properties

Fused deposition modelling (FDM) which trending nowadays became a very promising additive manufacturing technique to process polymers. Even though, FDM had achieved a remarkable development, the mechanical strength of its products still in arguable condition. Various researches have been carried out to study the effect of printing parameters on the mechanical properties of FDM parts. This research covers the investigation of the effect of printing parameters on the tensile properties of the acrylonitrile butadiene styrene (ABS) printed parts using FDM technique to identify the optimum printing parameters. Implementation of this research comprises of printing of tensile test specimens using ABS thermoplastic according to ASTM D638-Type 1 standard with combinations of different raster angle and infill percentage. Tensile test is then performed to analyse the mechanical performance of the printed parts. The optimum parameter to print with the combination of ABS and FDM is discovered. The optimum raster angle and infill percentage to print using ABS and FDM are 55° and 80% respectively. The specimen printed with those parameters achieved the highest ultimate tensile strength, elastic modulus and yield strength which are 33.78MPa, 25.17MPa and 787.68MPa respectively.
