I know. You could already place the printed board into a copper plating bath for a few seconds and get 100% bulk copper and solderability because the board will already be conductive where the traces are.

I am pretty sure that once there is a masking layer printed over the copper traces adhesion for the traces won´t be a problem, the pads I will have to see. I want to print the copper onto semi cured layers of the dielectric when they are still sticky so I hope that they will be held from the bottom.

I suppose you know Voltera: https://www.voltera.io/
and have taken a look at their approach.

They specify resistivity as 12mOhm/sq at 70 um. Equivalent copper is about 0.25mOhm/sq. This is 50x worse, meaning completely useless for most purposes, at least without extra precautions during design.

This is something you need to look at with silver ink devices. A huge trap, because such a number is not advertised clearly.

What about using a DLP such as the DLP3010, to image over the PCB. (put it on an XY table for imaging larger pcbs with higher accuracy/resolution.)

Yes, this is pretty bad. But "useless for most purposes" is a bit of a stretch...

Anyway, I'm not advocating Voltera whatsoever, I was just making sure the OP knew what he was "competing against" and that they had searched for "prior art" properly.
It's always good to do so when starting an ambitious new project.
