Description

technical field [0001] The invention belongs to the field of advanced manufacturing technology, and relates to a three-dimensional printing device for electric field-induced assisted electrospraying. Background technique [0002] With the improvement of device performance and integration, the functional structure of the device has gradually developed from a two-dimensional structure to a three-dimensional structure. For example, the three-dimensional micro-electromechanical system based on the cantilever beam structure provides a larger bandwidth and adjustable frequency than the two-dimensional system; compared with the macro-optoelectronic device, the micro-optoelectronic device is not only small in size, light in weight, but also low in power consumption. Therefore, the micro / nano three-dimensional structure plays an important role in the miniaturization, integration, and energy saving of high-performance devices. In addition, as the sensing unit of high-performance devi...
