3-D-printed structures 'remember' their shapes
Engineers are using light to print three-dimensional structures that 'remember' their original shapes. Even after being stretched, twisted, and bent at extreme angles, the structures -- from small coils and multimaterial flowers, to an inch-tall replica of the Eiffel tower -- sprang back to their original forms within seconds of being heated to a certain temperature 'sweet spot.'
