Within the next 80 years, our lives may be changed beyond recognition by 3D printing. It has already affected many things in our lives, right down to the food we eat. For instance, some restaurants in London have served 3D-printed hamburgers to customers.
But perhaps the most significant success that people have achieved to date is in medicine. They have made human body parts, including a beating heart, with 3D printing technology. And it is not just humans who are benefiting - in Brazil,people have given a new3D-printed shell to a turtle injured in a forest fire!
