Dental 3D printing device

The utility model relates to the technical field of dentistry, in particular to a 3D (three-dimensional) printing device for dentistry, and solves the technical problems that in the prior art, after a printer prints a tooth, the tooth needs to be taken out for a certain time and needs to be quickly completed by a skilled technician to enable the printer to quickly work to print the next tooth, time and labor are wasted, and the printing efficiency is high. And meanwhile, the processing efficiency is reduced along with the reduction of the physical power of technicians, and if a plurality of 3D printing heads are purchased, the production cost is increased. The dental 3D printing device comprises a bearing plate and a scanning device, the center of the top of the bearing plate is detachably connected with a processing cover, the top of the processing cover is provided with a 3D printer, the 3D printer is connected with the top of the bearing plate through a supporting frame, and the top of the bearing plate is
