The rapid evolution of 3D printing has made it possible to print practically any object in three dimensions. It's the beginning, some say, of a new industrial revolution.
We head to the United States, where the technology is already speeding up the way we do medicine, making the previously impossible now possible. Whether it's saving a baby's life using a device to restore breathing or creating an exoskeleton for children suffering with neuromuscular disorders, 3D printing is significantly impacting lives.
While these developments are exceeding expectations, the most exciting era may be still to come. At the Wake Forest Institute for Regenerative Medicine in North Carolina, researchers are printing spare body parts using biological cells as the ink inside these high-tech machines. We find out more.
