The utility model provides a micro-nano three-dimensional printer based on near-field electrospinning direct writing technology. The printer comprises a printer main body, a high voltage supply, a driving power supply, a motion controller, a CCD high speed image acquisition system, a computer and an auxiliary electric field controller. According to the micro-nano three-dimensional printer, a required relative position is chosen for molding through a 4-DOF platform and a nozzle with Z-direction freedom, conductive liquid drops are jetted at a high speed through a high voltage electrostatic field, the charged liquid drops are tracked and fed back by the CCD high speed image sensor, the charged liquid drops are controlled by an auxiliary electric field, the size of the auxiliary electric field is analyzed by a calculator, and the intensity of the auxiliary electric field is controlled by an auxiliary electric field controller. According to the micro-nano three-dimensional printer, the positions of liquid drops are controlled through the auxiliary electric field employing the static spinning direct writing technology, thereby micro-nano three-dimensional rapid molding is realized.
