Description

Rapid advancements in the emerging field of Additive Manufacturing Electronics (AME) over the past several years provide an innovative and cost-effective solution for the fabrication of multifunctional, frequency-selective composites that can be implemented for a variety of applications in avionics and electronic warfare. The overall aim of this study is to explore two different fabrication techniques (hybrid FDM versus conformal conductive ink) to create a 3D printed antenna and measure the corresponding signal strength, bandwidth, and polarization for each method. New hybrid metal-infused 3D printer feedstock filaments offer a compromise between ultra-lightweight, elastic polymers with relatively low conductivity and melting points, and full metal parts produced through much more expensive additive processes such as laser-powder bed fusion. 3D printing with metal-infused filament comprises an emerging new field coined “metal deposition modeling”, which when combined with dual-extrusion processes, provides an innovative strategy for creating multifunction, multi-layer, multi-material electronic devices with distinct conductive, dielectric, and substrate layers. By comparison, high resolution deposition of thin-film, nanoparticle silver and dielectric inks onto flexible substrate layers provides a revolutionary fabrication technique for flexible, conformal 3D printed circuit boards (PCBs).
