The invention relates to a three-dimensional printing device and three-dimensional printing head based on eddy current field compensate heating, and belongs to the technical field of rapid prototyping. The three-dimensional printing device includes a rack, a control unit and the printing head installed on the rack, and the printing head includes a heating block, and a printing nozzle installed atthe lower end of the heating block; the printing nozzle is made of double-layer metal materials, ferromagnetic conductive continuous structures are in the circumferential direction of the printing nozzle; the side wall of the printing nozzle is fixedly connected with a temperature monitoring sensor to output a temperature monitoring signal to the control unit; the printing head heating block includes an alternating field generator module installed on the outer side of the printing nozzle, and the module is of a curved concave plate structure; and the control unit includes a drive circuit usedfor supplying electric energy to the alternating field generator module. A heating module is added based on the eddy current field compensate heating on the printing head, the blockage of printing nozzles of different sizes can be effectively avoided, and the printing head can be widely used in additive manufacturing.
