It's not just paper that we can print on. Technology has progressed so much that we can now print objects too!
A model of an object is fed into a computer. The computer analyzes it and then instructs a 3D printer to print the object using the same dimensions as the model. And then, in a matter of some time (depends on how large the object is), out pops a three dimensional object from the printer!
How cool is that? The video below shows you how 3D printing works and more.
