Yes, currents can be high as they directly correlate with build rate. But the voltages are typically low, making it a lower power process than one would think.
100-1000x faster than a typical electroplating process

What kind of currents do you need?
I've considered the idea before and it seemed to me that since you need a fixed number of electrons for every metal ion you deposit that the currents end up being huge.
Also deposit speeds tend to be slow. How fast can your process layer metal (say in grams per hour)?
