Have you ever heard of 3D printing? It is a cool new technology that lets you basically xerox an object and it will make a copy of the object. There are even printing shops that will let you send them an object, or render an object on your computer and send them the file. Then the 3D object will be "printed" on their end and they will ship it to your front door! I had not known this existed until I saw it on the Discovery channel recently. I did a search and this company called "Shapeways" will print whatever you design. I think this is a cool concept and opens doors for people who are inventors and creative and have an idea and just want to get it out there.
Can you think of any other ways that 3D printing could come in handy?
