| Abstract Scope |
Alloying different metals has proven effective in optimizing material properties, including mechanical strength, plasmonic resonances, and corrosion resistance. Achieving precise control over the chemical composition of alloys is of paramount importance for many applications. However, several sub-micron resolution additive manufacturing techniques face challenges in fabricating a wide range of compositions. In this study, we leverage droplet-confined electroplating through electrohydrodynamic printing (EHD-RP) to develop a range of alloys that can be deposited into 3D geometries. Using aqueous mixed metal salt solutions, we demonstrate the ability to precisely control the composition of fabricated alloys. Microstructural investigation reveals a kinematically controlled deposition process. Nanoporous Ag with ligaments <100nm can be produced from our fabricated CuAg alloys, showing promising potential for surface-enhanced Raman spectroscopy applications. This innovative approach offers a pathway towards the development of tailored alloys with controlled compositions using small-scale additive manufacturing methods. |
