With the increasing demand for safer and more flexible technologies, the development of soft robots has become one of the key trends in robotics. Soft robots can be manufactured using additive manufacturing (AM) methods, particularly fused deposition modelling (FDM), due to its flexibility in printing complex geometries. Styrene butadiene styrene (SBS) is a material with elastic properties and re-meltability. Therefore, SBS is suitable for use as FDM filament and for soft robot applications. In this study, SBS filaments were fabricated for FDM to be applied in soft robots. The fabrication process utilized the ram extrusion method with variations in track length, track diameter, and temperature parameters. The SBS filaments were measured and subjected to tensile tests to observe their dimensions and characteristics. The test results were compared to assess the effect of parameter variations, and the most optimal parameters for filament fabrication were selected. The results showed that SBS filaments could be fabricated according to the diameter specification of 1.75 ± 0.05 mm. Based on statistical analysis, parameter variations ack length of 7.08 mm, a diameter of 1.97 mm, and a temperature of 200°C was identified as the most optimal parameter in this study. The SBS filaments produced in this research can be used for AM processes and demonstrate potential for application in soft robots based on their mechanical properties.
