AI Technical Summary

Problems solved by technology

The working voltage applied by the electrohydrodynamic jet printing equipment is generally hundreds of volts to several thousand volts. When a certain input voltage is input, the actual voltage rises or falls to the input voltage value. Due to the influence of the hardware circuit, it takes a long time In the closed-loop control process of near-field electrohydrodynamic jet printing, a larger delay time will have a greater impact on the quality of near-field electrohydrodynamic jet printing patterns.
