The shape of things to come: 3D printing

Twenty years ago, printing replacement organs, human skulls and three course meals seemed like the stuff of science fiction. But in 2013, architects in Amsterdam are building a 3D printed home; scientists in Scotland have proved they can print embryonic stem cells and aircraft manufacturers are working on ways to construct 3D printed planes. By 2025, it’s estimated that the 3D printing industry will be worth $8.4 billion, and US President Barack Obama believes it will be the next revolution in manufacturing.
