This looks like something I toyed with in 2016, but (as you may expect from my lack of relevant experience and qualifications) all I found were what Edison called "ways to not make a lightbulb".
The:

in particular is what I wanted to experiment with, because something like this clearly allows parallelisation of the build process in much the same way photopolymerisation is faster than FDM.
I can find my paper and post it but keep in mind it was a "undergraduate thesis" and something I spent only a very finite amount of time on.
how did your project go?

From what I heard the state of the art was to move away from electrodes and to use lasers. So how that works is that you have the normal electrolytic solution but you apply a passive voltage below the activation voltage. Then you use the laser to break down the double layer at the substrate surface. This leads to laser controlled deposition.
i feel like it's probably easier to have 1000 electrodes than 1000 lasers tho
• SLA resin printers use a superfast/accurate motorised mirror to direct the laser where its wanted
• mSLA resin printers use a strong light source instead of a laser + an LCD to mask the area they don't want exposed
