| Abstract Scope |
Localized electrodeposition in liquid (LEL) enables freeform printing of 3D metal microarchitectures and has the potential to transform several research fields, including micro-/nanomechanics and microelectromechanical systems (MEMS). In this talk, the recent developments using the LEL technique will be presented. Specifically, by altering the printing parameters, the microstructure of the copper microarchitectures can be tuned from microcrystalline (~1-2µm grain size) to nanocrystalline (~40nm grain size). This microstructure change can be effected on-the-fly; consequently, the mechanical properties of metal microarchitectures can be tuned locally with microscale spatial precision. Another unique design possibility of the liquid submerged printing process is the encapsulation of liquids inside the metal microarchitectures. This opens up potential applications as tunable strain sensors or as a means of enhancing the mechanical properties, especially under cryogenic conditions. Furthermore, LEL allows the fabrication of customizable metallic micro-/nanoscale tensile and shear testing platforms, and example case studies will be presented. |
