Direct inkjet printing with silver nitrate and vit C.
Very very cool.

I read this article as Fred suggested.
I wondered if this approach would work with tin nitrate as well.
Or perhaps a combination of silver nitrate and tin nitrate.
Perhaps printing on some substance that did not melt at the melting
point of tin or silver.  Then heat the surface to reflow and maybe form
an alloy.  Maybe with a laser ?
Any ideas out there ?

Silver   Melting Point: 961.93 °C (1235.08 °K, 1763.474 °F)
Tin — Melting Point: 231.9 °C (505.05 °K, 449.41998 °F)
Silver solder is alloy of silver and tin
Silver and Tin nitrate are water soluble
