A new research paper maps how laser additive manufacturing is bringing shape memory alloys closer to practical 4D printing.

Researchers have developed a novel copper-based alloy that exhibits a special shape memory effect at temperatures as low as -200°C. The work has been published in the journal Communications ...

Shape memory alloys (SMA) remember their original shape and return to it after being heated. Similar to how a liquid transforms into a gas when boiled, SMAs undergo a phase transformation when heated ...
