| Abstract Scope |
Additive manufacturing (AM) combined with nanoelectrochemistry is an emerging approach to achieve complex fabrication at micro- and nanoscale. The underlying principle is electrochemical confinement that is created for a precise metal ion reduction on a conductive substrate via electroplating, allowing to convert liquid metal precursor “ink” into solid material. This idea is realized in a meniscus-confined electrodeposition (MCED) configuration, where electroplating occurs in a scanning droplet cell. Potentially, MCED can provide sub-10 nm resolution and fast deposition rates, but without appropriate deposition monitoring and feedback, the potential of MCED remains hindered, especially for the AM at the nanoscale.
Here, we present a new generation of MCED that overcomes these challenges by maintaining a constant meniscus achieved by a mechanical resonator. This allows to overcome the issues related to both the reduced deposition rates (in intermittent meniscus MCED) and thus increase the fabrication speed and allow for high printing resolution. |
