'4-D printing' a new dimension for additive manufacturing

Researchers have demonstrated the 3-D printing of shape-shifting structures that can fold or unfold to reshape themselves when exposed to heat or electricity, an approach also known as '4-D printing.' The micro-architected structures, including boxes, conductive devices, and a stent, were fabricated from a conductive, environmentally responsive 'smart' ink.
