Now we only need help from Ray Palmer and his Atom suit in order to shrink it down to a size where it's usable :-) I think the route of trying to produce a photoreactive polymer is more promising...

Photoreactive dopant accepting polymer would really be a game changer tho. Otherwise we could try to "just" scale down a normal additive printer design to a micrometer scale... It will require multiple nozzles tho, because we need to feed more than just one material... p-doped, n-doped and isolator...
the creator of this - which i thoroughly recommend (it has a 40:1 wormdrive built-in and an automotive-grade flexible driveshaft)
https://flex3drive.com/product/g5-flex-extruder/
also created a dual-extruder head (2-in to 1-nozzle).
there do exist triple extruders https://www.matterhackers.com/store/printer-accessories/polystroooder-tri-ho tend-1.75mm
i am assuming of course that the material being "fed" comes in the standard 1.75mm extrusion roll, which, duh, may not actually be the case, duh.
