Interesting post Caitlin. I am very intrigued to see what the development of 3D printers will bring. I have heard people say that they will be misused for weapons, although I believe and hope they will be primarily used for good. I have read a lot how they will be able to make human body parts from them, which I think will be amazing. I therefore think that making them available in some libraries we are encouraging innovation that can produce astounding results.
