This article presents a method for manufacturing a frequency selective surface (FSS) using the 3D printing technology, including material characterization, design, fabrication, and evaluation. The FSS design is based on a three-layer structure. The first layer is a 3D printed lossy material, the second layer is an air gap, and the third layer is a ground plane. By changing the geometrical parameters of the 3D printed layer, it is possible to tune the frequency of the absorption band of the FSS.
