The invention discloses a transmission device of a 3D printer with a low degree of freedom parallel structure, which relates to the technical field of 3D printer appliances; the device comprises a guide pulley and a magnetic ball head connecting rod sleeve, and the two ends of the magnetic ball head connecting rod are respectively connected with the pulley on the printer extrusion head effector receiving plate and the slide block. The symmetrical structure of the two ends of the magnetic ball-end connecting rod connects the strong magnetic with holes, and the encapsulation lubrication in the strong magnetic hole is not full of all the inner holes. Because of magnetic adsorption, the magnetic field between the ball-end and the strong magnetic field is not completely contacted. The strong magnetic field is wrapped by a non-magnetic hollow cylinder with the same height, so as to prevent the influence of the magnetic force on the structure. The hollow cylinder is installed at one end of the extruder effector of the printer and at the On the pulley, the pulley is fixed on the slider, the back of the slider is equipped with magnets, the electromagnetic guide rail is equipped with electromagnetic coils, and the slider is adjusted for magnetic levitation motion due to magnetic force, thus constituting the printer transfer motion system as a whole. The new device completely eliminates the friction between the rod end spherical pair and the slider and the guide rail in the printing process, enlarges the rotation angle of the spherical pair, and realizes printing. Improvement of forming accuracy and extension of printing range.
