The invention discloses an ultrasonic vibration assisted 3D printing method, belongs to the technical field of 3D printing, and relates to a device and method based on ultrasonic vibration assisted 3Dprinting. According to the method, the specially-made ultrasonic-assisted 3D printing device is adopted, and the device is composed of a 3D printing mechanism and an ultrasonic vibration structure. According to the ultrasonic vibration assisted 3D printing method, the 3D printing device is assembled firstly, and when ultrasonic vibration is assisted for 3D printing, firstly, a printing material is fed into a printing nozzle through a stepping motor; the printing material in the nozzle is converted into a molten state from a solid state under the action of a high temperature and is extruded toa printing bottom plate through the nozzle; and at the moment, under the control of a six-degree-of-freedom mechanical arm and an ultrasonic generator, an ultrasonic amplitude-variable rod carries out the ultrasonic vibration
