As the printing press helped to forge the way for freedom and the increase of knowledge in our history. I believe the 3D printer will usher in a new type of freedom. The freedom to create whatever you may wish or dream up. In light of the recent and current gun ban proposals, Defense Distributed is in the process of creating a sharable file to print a working gun on a 3D printer. They have tested an AR15 that was built with a lower receiver that was printed on a 3D printer. It successfully fired 6 rounds before it broke. While it may seem as though a printed gun is too fragile to be useful, the technology is still new and developing rapidly. Also new technologies are emerging to print in different medias such as different polymers, glass, stone, ceramic and various metals. It will be near impossible to keep guns away from people if they can be printed at home.                                                                             http://defensedistributed.com/about-us/                                               http://www.forbes.com/sites/andygreenberg/2012/12/03/heres-what-it-looks-like-to-fire-a-partly-3d-printed-gun-video/                                                                                                                          These Printers are becoming available to hobbyists for prices ranging from $2200 dollars and up. Larger more expensive 3D printers are being made that will print in more than one media at the same time. As these 3D printers become more widely used, greater capability will be available at lower cost to the home hobbyist, or anyone for that matter. Soon a 3D printer may be as common in our homes as microwave ovens and computers. Similar to the replicators on Star Trek Next Generation, 3D printers will be able to create many household items we currently use, for example you may want to design and print parts for a lamp and assemble it yourself. At least one company, RepRap, plans to build a 3D printer that can print copies of itself, making it a self replicating printer. It is already capable of printing some of its parts and work is underway to complete the task.  Fab@Home printer lists chocolate as one of its printable medias. As this technology evolves, who knows what may or may not be possible. Consider that we may soon be able to print medicines or household chemicals or maybe a part to repair your car. How about a replacement hip where the ball is permanently made into the socket. The possibilities are almost endless.    http://fabathome.com/                         http://en.wikipedia.org/wiki/RepRap_Project             http://www.stratasys.com/Products/Overview.aspx  http://en.wikipedia.org/wiki/3D_printing
