Presentation Title A-94: 3D Additive Manufacturing of Metals at Micro/Nanoscale Using Localized Electrodeposition

On-Site Speaker (Planned) Majid Minary
Abstract Scope We present an additive manufacturing technique for deposition of pure metallic micro/nanostructures. This research is supported by US Navy under Young Investigator program (ONR-YIP). In this technique a glass capillary with a few micron to sub-micron tip is filled with the electrolyte of a metal of interest. A liquid capillary formed between the tip of the pipette and the conductive substrate completes the electronic-ionic circuit. Upon application an appropriate electric potential metal ions reduce and get deposited on the substrate. The pipette is steered precisely in 3D using precision nano-positioners, which results in formation of desired 3D objects from a CAD file. The process is mainly driven by evaporation of the liquid in the meniscus bridge. We present fabrication of various metallic structures, as well as characterization of their materials, mechanical an electrical properties. A Multiphysics computational model will be also presented to explain the detailed mechanisms governing the process.
