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 new 3D-printed shell to a turtle injured in a forest fire!
