Technical Field

[0001] The utility model relates to the technical field of 3D printing, in particular to a lifting mechanism for 3D printing equipment. Background Art

[0002] 3D printing has brought about a revolution in the global manufacturing industry. In the past, component design was completely dependent on whether the production process could be realized. The emergence of 3D printers will overturn this production idea. This will allow companies to no longer consider production process issues when producing components. Designs of any complex shape can be realized through 3D printers.

[0003] However, the lifting mechanism of the existing printer can only adjust the height of the printing plate, but cannot discharge the finished product after printing. Workers are required to reach under the printer to remove the finished product from the surface of the printing plate. Because the material at the bottom of the finished product is too firmly attached to the surface of the printing plate, and the printing plate is located below the print head, it is not convenient for workers to remove it, thereby reducing printing efficiency. Therefore, a lifting mechanism with adjustment function is needed for 3D printing equipment. Utility Model Content
