Complexobjects that were difficult or impossible to produce using standardmethods can now be manufactured.There is significant interest in applying 3D printing technology toaerospace applications. It is very probable that future RFcomponents will be integrated into 3D printed parts.This paper describes the transmission performance of full-metal(volumetric) frequency selective structures and compares them withthose of 3D FSS made by partially metallizing the same 3D shapes,thereby controlling induced current paths. 3D printing is used hereto fabricate the core of the structures [1], which are based around anew concept of folding FSS elements in three-dimensions [2].IntroductionB.
