Novel 3D printed synthetic dielectric substrates

Abstract

This letter presents dielectric properties of air filled synthetic substrates fabricated in a single process using three‐dimensional printing. The permittivity and loss tangent of a given sized substrate can be changed by controlling the air infill volume fraction. © 2015 Wiley Periodicals, Inc.

Achieving improved dielectric, mechanical, and thermal properties of additive manufactured parts via filament modification using OMMT-based nanocomposite

“…The technology has an edge over other manufacturing processes in regard with shorter manufacturing lead time and ability to produce complicated geometries; however, there is scarcity of information about electrical properties of new AM materials which can be utilized for RF applications. The dielectric properties such as relative permittivity and loss tangent of AM parts can be controlled to some extend by manipulating the internal structure of the substrate [6]. However, the permittivity cannot be increased in this case as the presence of air inside the structure will lower the permittivity.…”

3D printing, inkjet printing and embroidery techniques for wearable antennas

“…Furthermore, by varying the internal structure, we can alter the dielectric properties. If air inclusions are added inside a host material the relative permittivity is reduced [19]. If metallic or high permittivity inclusions are added in a matrix, then the permittivity can be increased [20], [21].…”

3D printed dielectric Fresnel lens

“…The dielectric materials can be custom-made by using 3D Printing [12]. By adjusting the infill percentage of the 3D material, it can create materials with bespoke structures with customised dielectric constant values.…”
