Abstract

Plastic waste, particularly Polyethylene Terephthalate (PET) from mineral bottles, poses an environment challenge but can be reused as filament for Fused Deposition Modelling (FDM) 3D printing. This study

investigates the effect of temperature and stepper motor rotational speed on tensile strength of recycled PET filament and to determine the optimum process parameters. The experimental design employed the Taguchi method using the Taguchi L₄ orthogonal array with two factors and two levels. The parameters were temperature of 210℃ and 220℃ and rotational speed of 18 and 24 rpm. The total of 12 tensile specimens using a Haltech H-01 Cartesian 3D printer and tested to ASTM D638 Type IV. The result showed that the highest tensile strength was 56,9 Mpa in experiment 3, while the lowest was 49,7 Mpa. S/N Ratio analysis indicated that rotational speed was the most influential parameter, with the optimum combination obtained at 210℃ and 18 rpm.
