Resin-enhanced fused deposition modeling three-dimensional printing system

The utility model discloses a resin reinforced fused deposition forming three-dimensional printing system in the field of three-dimensional printing, which comprises a fixed substrate, and a printing nozzle is arranged in the middle of the fixed substrate in a penetrating manner. When three-dimensional printing is carried out through the printing spray head, the resin spray head can be driven to move along the track of the printing spray head through the action of the micro servo motor under the transmission of the outer gear and the outer gear ring, and a layer of photosensitive resin is synchronously coated on the basis of fused deposition printing; according to the method, the three-dimensional model is filled with the photosensitive resin, then the photosensitive resin is rapidly cured through the ultraviolet light curing lamp, so that the overall strength of the three-dimensional model is improved, the cracking risk between the layers is reduced, and compared with a traditional fused deposition process,
