[0002] 3D printed nested illuminated advertising signs are manufactured using 3D printing technology to create uniquely nested lighting fixtures. Different fonts, characters, and patterns can be effectively created through 3D printing according to customer requirements, and the lighting effect can be controlled. However, during use, it is inconvenient to control the stability of the nesting and it affects the display effect of the illuminated advertising signs.

[0003] To overcome the aforementioned shortcomings, existing technology (Chinese patent application CN202023273143.X, filed on 2020-12-29) provides a novel 3D printed three-dimensional illuminated letter. By movably installing a protective plate on the top of the illuminated letter shell, the plate effectively protects the shell from damage caused by falling objects. Springs provide cushioning, preventing significant vibrations from impacts and reducing the impact on the illuminated letter shell, thus extending its service life. A fixing sleeve is fixedly installed on the inner wall of the mounting groove, allowing for easy installation and fixing of the illuminated letter shell by operators. Disassembly is also convenient, improving ease of use. While existing technology can achieve quantitative material feeding, it is inconvenient to perform stable nesting and positioning during operation, affecting the assembly effect of the inner and outer shells and impacting safety and stability.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing 3D-printed nested illuminated advertising signs. Utility Model Content
