Researchers at the University Medical Centre Utrecht are experimenting using stem cells in 3D bio-printing.
It is hoped one day the technology could make it possible to print replacement body parts or organs.
BBC Click's Jen Copestake went to the Netherlands to meet some of the scientists working on the project and find out more.
