Abstract: A recently developed additive manufacturing method called melt electrowriting (MEW) is utilized to print at the microscale for tissue engineering purposes. The MEW process highly depends on various printing parameters such as processing temperature, applied voltage, printing speed, melt flow rate, and nozzle diameter which play an important role in the quality of printed scaffolds. In this study, the Taguchi method is applied to achieve the best conditions for printing high-resolution scaffolds with the smallest fiber diameter and the best uniformity. Finally, using the Taguchi method, we performed 16 experiments with different conditions. The results showed that to print a fiber layer with the smallest desired diameter and the best uniformity, the desired printing conditions should be such that the process temperature is 230 °C, the voltage is 4000 V, the printing speed is 100 mm/s, and the melt flow rate is 5 µl/min and the inner diameter of the nozzle is set to 200 µm.
