3D printing has grown in sophistication since the late 1970s; TED Fellow   
   Skylar Tibbits is shaping the next development, which he calls 4D printing,   
   where the fourth dimension is time. This emerging technology will allow us to   
   print objects that then    
   reshape themselves or self-assemble over time. Think: a printed cube that   
   folds before your eyes, or a printed pipe able to sense the need to expand or   
   contract.
