3D printers are changing the world

THE DAY WHEN WE ALL HAVE 3D PRINTERS AND MAKE ALMOST ANYTHING WE WANT IN OUR OWN HOMES HAS NOT COME YET. BUT, IN OTHER WAYS, THE TECHNOLOGY IS ALREADY REVOLUTIONIZING THE WORLD AROUND US...

Medicine:
It has now become normal for doctors to use 3D printers for reconstructive surgery by creating exact replicas of individual bones. After the first headline-making cases of this happening, the technology has rapidly become commonplace, with replacement bones being manufactured overnight for surgery the next day. A revolution is also happening in the area of prosthetics, where cheap, individualized body parts have become possible. But the future applications come straight from the world of science-fiction. 3D bioprinters are in development that can work with organic materials to print, for example, human skin. And it's going to happen sooner than people think- a 2015 survey of 800 tech experts found that 76 per cent of them believe that the first transplant of a 3D-printed human organ will happen by 2025.
