The present invention discloses an integrated method for fabricating a frequency selective surface (FSS) for a complex curved cavity structure. This method utilizes multi-process composite 3D printing as a technical approach, employing FDM technology to fabricate a water-soluble substrate. 3D direct writing technology is then used to create an inner FSS pattern on the substrate surface. The cavity structure itself is then printed on top of the substrate, and an outer FSS pattern is then created on the surface of the cavity structure. The water-soluble substrate is then dissolved, ultimately resulting in a complex curved cavity FSS structure with frequency selective patterns on both the inner and outer surfaces. Furthermore, through the practice of this invention, surface treatment measures are required for the 3D printed structure before fabricating the FSS pattern, improving the quality and precision of the FSS metallization pattern and ensuring the integrated fabrication of the complex curved cavity structure and the inner and outer FSS patterns.
