Abstract

Additive manufacturing by fused deposition modelling (FDM) now offers some useful performance for functional materials including conductors. Whilst this technology enables the creation of truly three-dimensional (3D) composite structures its accuracy and resolution are not yet so refined as those of 2D fabrication methods. Moreover, dielectric and metallic filaments used in FDM have complex material properties that depend on print parameters and usually exhibit higher losses than RF substrates and bulk conductors. In this work we investigate by simulations and experiments several magnetic meta-atom variants with a view to developing optimal designs for the successful production of metamaterials at microwaves with FDM techniques. Conductor thickness is shown to be a useful new design parameter to reach the desired degree of miniaturization and resonance quality factor of the meta-atoms at low print resolution.
