| Abstract Scope |
Traditional printing of metallic nanostructures requires complex ink formulations and post-deposition thermal treatments, resulting in multi-stage workflows. Plasma Jet Printing (PJP) is a direct-write additive manufacturing technique that enables rapid, on-demand deposition of functional inks and in-flight reduction of salt-based inks through exposure to a reactive plasma environment, eliminating the need for extensive ink formulation strategies or post-processing. Here, we demonstrate the fabrication of metallic nanostructures by atomizing an aqueous metal formate ink and reducing it during plasma-assisted deposition. A parametric study is performed to investigate the influence of plasma power, substrate temperature, and ink concentration on the resulting film morphology and electrical properties. Results show that careful control of these parameters enables the direct formation of metallic films and nanostructures with minimal post-deposition treatment. The relationships between processing conditions, structure, and function are discussed to highlight PJP’s potential for rapid fabrication of complex functional structures from simple precursor inks. |
