Resumen
This project presents the electrical characterization of state-of-the-art material Multi3D's Electrifi 3D conductive filament, a nanocomposite. Since its exploration in 2017, numerous applications in RF circuits and antenna fabrication through additive manufacturing processes have been published. An area of use in electromagnetic interference shielding has been identified for this Electrifi filament but has yet to be properly characterized. This project aims to find a correlation between additive manufacturing printing parameters and electromagnetic interference shielding for Electrifi filament. For this purpose, 2 different Electrifi grid structures were designed and fabricated. Measurements of conductivity, impedance and the S11 and S21 parameters were taken to determine the performance of the Electrifi shields with different design configurations. The results point out that the definition of the printing parameters has a strong influence on the conductivity of the resulting 3D printed Electrifi meshes, producing remarkable variations at the electromagnetic interference shielding performance along with aperture dimensions on the grid.
