 Dear classmates as Prof.Sugai mentioned 3D , im exploring about it more and more. I might carried on it little to deep and sharing too much not,if yes sorry. This presentation could help you to understand it more.My comment here is its truly an amazing innovation. Most importantly its the Future i think,along with it also rises many questions such as once if u download the data u can just keep printing and printing ,open source or what will happen to the things like IDs as UNIQUE... etc . But the next presentation will SHOW you that it has already made a change in someones life and will make more.After all nothing is important than human life! http://www.ted.com/talks/lang/en/anthony_atala_printing_a_human_kidney.html
