MIT Develops 3D-Printed Objects with Mechanically Switchable Surfaces
MIT researchers have developed a system called ShiftLens, enabling 3D-printed objects to change appearance without electronics. The system uses optical layers to create dynamic visual effects, allowing objects to indicate proper usage. This innovation simplifies the creation of interactive objects, offering applications in packaging, signage, and prototyping. ShiftLens combines special lenses with patterned backplanes, providing a mechanical method for visual state changes.
