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.
3D printing also provides an opportunity to reexamine the way we think about intellectual property. The direct connection that many people make between "digital" and "copyright" is largely the result of a historical accident. The kinds of things that were easiest to create and distribute with computers – movies, music, articles, photos – also happened to be the types of things that were protected by copyright. Furthermore, it happened to be that the way computers distribute things – by copying – was exactly the behavior that copyright regulated. As a result, copyright became an easy way to (at least attempt to) control what people were doing with computers.
That connection between copyright and digital begins to break down as one moves away from movies, music, articles, and photos, and towards gears, cases, robots, and helicopters. As the connection frays, it serves as a reminder that not everything – not even every digital thing – is protected by copyright. In fact, most (but by no means all) physical objects are not protected by any type of intellectual property right. That means that anyone is free to copy, improve, distribute, or incorporate those objects as they see fit.
This freedom is not a new development, nor is it a loophole. 3D printers do not take away intellectual property rights any more than computers grant them. But they do provide an opportunity for people to reexamine old assumptions about how the system works.
