[0002] A 3D printer, also known as a three-dimensional printer, is a rapid prototyping process that uses layer-by-layer stacking to create a three-dimensional model. Its operation process is similar to that of a traditional printer, except that traditional printers print ink onto paper to form a two-dimensional flat drawing, while a three-dimensional printer stacks liquid photosensitive resin materials, molten plastic filaments, gypsum powder and other materials layer by layer through spraying adhesives or extrusion to form a three-dimensional entity.

[0003] In order to prevent external electromagnetic signals from interfering with the normal operation of 3D printers, wireless signal interference shielding covers are often set outside the control circuit board of the 3D printer to ensure the subsequent printing accuracy and quality of the 3D printer. However, the existing shielding covers still have the following problems: 1. The existing shielding covers have multiple fixed specifications and need to be customized according to the specifications of the control circuit board. They cannot be quickly adjusted according to the specifications of the control circuit board. They have low applicability and high customization costs. In addition, the shielding covers cannot be disassembled for reuse, which increases the subsequent upgrade and transformation costs. 2. In order to ensure strength, the wall thickness of the existing shielding covers is relatively thick, which increases the overall weight of the shielding covers, increases costs, and has poor protection performance.
