Description

Technical Field

[0001] The utility model relates to the technical field of printer frames, in particular to a sheet metal frame for a 3D printer. Background Art

[0002] With the development of society, especially the progress of science and technology, the rapid development of social productivity has been greatly promoted. In particular, the continuous improvement of printing technology represented by 3D printing has provided a strong boost to the development of society. For example, the patent with publication number CN214294482U discloses a sheet metal frame of a 3D printer, including an optical axis guide rail, an upper sheet metal frame and a lower sheet metal frame. The upper sheet metal frame and the lower sheet metal frame are fixedly connected by four sheet metal columns, and the two ends of the optical axis guide rail are fixedly connected between the upper sheet metal frame and the lower sheet metal frame by bolts. There are four optical axis guides, which are respectively located on both sides of the sheet metal upper frame. The four optical axis guides are movably sleeved on the sheet metal platform. The optical axis guides and the sheet metal columns are fixedly connected by bolts between the sheet metal upper frame and the sheet metal lower frame. A modular design is adopted to enhance the overall strength and avoid deformation. However, the optical axis guides will also limit the sheet metal platform, making it inconvenient to remove the printed objects on the sheet metal platform and to clean the sheet metal platform, which may easily lead to some impurities remaining on the sheet metal platform, which may affect subsequent printing.
