[0002] The uniform dispersion of components and additives in the resin is crucial for the quality of 3D printing. Non-uniform resin may cause ripples, holes or other defects during the printing process. Therefore, in order to ensure the uniform mixing of the resin, a resin stirring mechanism for 3D printing needs to be designed;

[0003] For this reason, the patent with the publication number of CN220095574U discloses a material supply and stirring mechanism for 3D printing, including a housing. A stirring tank is arranged inside the housing, a buffer device is arranged inside the housing, a stirring device is arranged inside the stirring tank, a feed inlet is installed on the right side of the top of the housing, a discharge outlet is installed at the bottom of the housing, and support legs are fixedly installed on the left and right sides of the bottom of the housing. In this material supply and stirring mechanism for 3D printing, by setting the buffer device, the vibration generated by the stirring tank during stirring is reduced, so as to avoid the influence of vibration on the printer during the printing process and improve the printing accuracy. It solves the problem in the background art that when the motor drives the stirring rod to rotate during stirring, the stirring tank is likely to vibrate, resulting in the vibration of the printer during the printing process and affecting the printing quality. By setting the stirring device to process the impurities in the raw materials, the printing quality is improved;

[0004] Although the above-mentioned material supply and stirring mechanism for 3D printing can process the impurities in the raw materials during use, thereby improving the printing quality, the resin is viscous during stirring and will remain on the inner wall of the stirring body, which is inconvenient to clean. Therefore, a resin stirring mechanism that can scrape and clean the inner wall of the stirring machine body needs to be designed. Summary of the Utility Model
