They manage to use liquid metal 3D printing

The University of North Carolina developed a technique that allows you to print small parts in a , using as input a variant of liquid metal, which after being printed have a certain level of flexibility.

The liquid metal is comprised 75% to 25% Gallium Indium two nontoxic alloys which maintain their liquid state at room temperature.

Gallium slightly oxidized on contact with air, which makes it harden and produce a thin layer on the object-resistant lining. This property allows the object developed can lose its shape and recover without losing or undone.

According to the extrusion system used in the printing project, flexible bodies (interior and exterior Indian liquid gallium solid) are accumulated over each other creating a connection between the segments, which can receive information such as a cable network .

The research group of the University, named “The Dickey Group”, seeks to combine the liquid metal with other everyday flexible materials, such as rubber, to create structures that can warp or stretch but recover its original shape, and of greater overall strength. For now, this input costs more than 100 times the value of print 3D ABS plastic, so it will remain a draft until a subject which is not set if it ends meet.

What type of consumer electronics product could serve such a development? Phones?, Notebooks shutters, cars unbreakable?
