The university of Nottingham developed reversible information storage of 3 d printing materials
Jun 25, 2018

Recent studies have shown that at the university of Nottingham, the use of 3 d printing can produce contains response to environmental stimuli (e.g., light) and the state of the switch polymer materials.
  
This is a bottom-up device manufacturing method, will be in an unprecedented way to promote the development of increasing material manufacturing, adopt unique integrated design method of display full-color 3 d printing devices of the function between photochromic molecules and polymers in synergy, extend the toolbox of advanced materials, the team studied a light-sensitive molecules, when irradiated by the light from colorless to blue.Through exposure to oxygen in the air, color change can be reversed.

                                 Advanced materials containing photochromic properties
  
Then the researchers by combining photosensitive polymer molecules with custom 3 d printing materials, can produce reversible new material to store information.
