Researcher used 3D printing technology to create structures that “remember” their shape, actively transforming configurations over time in response to environmental stimuli. The video presents a
miniature Eiffel Tower that recovers shape after heating to 60?°C and 3D printed multimaterial grippers used to grab an object.
