3D-Printing with Liquid Metal at Room Temperature #cool

Article on CNET by +Amanda Kooser

«Researchers took a liquid metal alloy of gallium and indium at room temperature and made (...) a 3D figure. (...) The researchers have spent years developing a method of 3D-printing liquid metal at room temperature. (...) The process uses a syringe needle to dollop tiny spheres of metal together. A thin oxide skin holds it all together and prevents the printed structures from just collapsing into metal blobs. (...) The extruded wires are both flexible and stretchable, opening up possibilities for 3D-printing connections between electronic components (...) and even applications like headphone wires where flexibility and the ability to self-heal could improve durability.»

Seems we'll soon be making our own motherboards from blueprints :)
I cant wait I got some cool stuff I need to make ....yahoo
Not to be a troll, but it looks not quite ready for prime-time.  I'm a fan of multi-material 3D printing, but this looks too much like dripped solder. 
guess how much is the resistance value (ohms) of that resistor??? hehehehe!
