  Additive manufacturing can realize almost any designed geometry, enabling the
fabrication of innovative products for advanced applications. Local
electrochemical plating is a powerful approach for additive manufacturing of
metal microstructures; however, previously reported data have been mostly
obtained with copper, and only a few cases have been reported with other
elements. In this study, we assessed the ability of fluidic force microscopy
(FluidFM) to produce Ni-Mn and Ni-Co alloy structures. Once the optimal
deposition potential window was determined, pillars with relatively smooth
surfaces were obtained. The printing process was characterized by printing
rates in the range of 50-60 nm/s. Cross-sections exposed by focused ion beam
showed highly dense microstructures, while the corresponding face scan with
energy-dispersive X-ray spectroscopy (EDX) spectra revealed a uniform
distribution of alloy components.
