3D printing has totally changed the world. No one would ever have thought that 3D printing would be a possibility the way it is today. In 1983, the movie Weird Science showed a scene in that two guys managed to print a woman based on the information and images they had fed into a computer. 3D printing still has a long way to go, with its expensive and slow. Today 3D printing market value is $35.6 billion.
