... I've made some 'metal-printing' in past with a paste mixed with 30 microns big microspheres of gold(80%)+tin(20%) and Dexpanthenol and Aqua dest. as binder.
Dispensed the paste through a needle with 0.1mm ID and 'fired' the track with a 8Watt IR-diodelaser, similar to laser-brazing.
Should be similar with any other eutectic alloy, but you'll need Argon as shielding gas for non-precious metals ...
