π‘ 3D prints now show info without electronics
Researchers combined lenticular optics with 3D printing to create ShiftLens, electronics-free objects with changeable appearances. This system was developed by teams at MIT, Technical University of Munich, and Northeastern University. The technology allows objects to display high-resolution, discrete visuals, like telling if they are used correctly. One prototype acts as a meeting room display, while another warns when a bottle lid is incorrectly fitted. The next step involves scaling this up for applications like smart pipework systems. π‘
