3D printing provides an opportunity to change the way we think about the world around us.  It merges the physical and the digital. People on opposite sides of the globe can collaborate on designing an object and print out identical prototypes every step of the way. Instead of purchasing one of a million identical objects built in a faraway factory, users can customize pre-designed objects and print them out at home. Just as computers have allowed us to become makers of movies, writers of articles, and creators of music, 3D printers allow everyone to become creators of things.
