Technological progress has increased rapidly. Indonesia is no exception. One of the technologies that is increasing rapidly and is expected to continue to develop is printing technology. 3D Printing is a new development in the world of technology at this time. This study aims to obtain the geometric parameters that most influence the results of PET (Polyethylene Terephthalate) using a 3D printer and to obtain the optimum parameter optimization for the tensile test strength of the filaments of PET (Polyethylene Terephthalate) plastic which affect the magnitude of the tensile test. In this study the authors used a combination of shooting parameters in the form of nozzle temperature (200â°, 210â°, 220â°) cooling speed (20â°, 40â°, 60â°) printing speed (30mm/s, 35mm/s, 40mm/s) in this study the method used was Taguchi method. The results of this study are to determine the effect of nozzle temperature, printing speed, and cooling speed on the manufacture of 3D printing geometric objects to determine the effect on the shape of geometric objects that have been printed. In this study, geometric tests have been carried out and obtained optimal parameters for six different profiles according to the workpiece used, namely Bridging Nozzle Temperature 220 °C, Printing speed 40mm/s, Cooling speed 40 °C, Nozzle Diameter Temperature 220 °C, Printing speed 60 mm/s, Cooling speed 40 °C, Stringging Nozzle Temperature 220 °C, Printing speed 20 mm/s, Cooling speed 40 °C, Scale Nozzle Temperature 220 °C, Printing speed 60mm/s, Cooling speed 35 ° C, Hole Nozzle Temperature 220 °C, Printing speed 40 mm/s, Cooling speed 30 °C, Nozzle Tilt Temperature 200 °C, Printing speed 20 mm/s, Cooling speed 35 °C.
