3D printing transformed manufacturing by allowing objects to be built layer by layer. Scientists are now applying similar ideas to biology.
Bioprinting uses living cells and biomaterials to create tissue-like structures that could eventually help repair or replace damaged parts of the body.
Researchers are exploring applications in regenerative medicine, drug testing and personalised healthcare.
The technology is still experimental, but scientists have already produced simplified skin, cartilage and other tissue structures in laboratory settings.
Supporters believe bioprinting could reduce dependence on organ donors and improve testing methods by creating more realistic biological models.
Challenges remain significant. Living tissues are complex systems that require blood supply, structural stability and long-term function.
Experts say widespread clinical use may still be years away, but the field highlights how innovation is increasingly merging engineering with biology.
In that sense, future medicine may involve not only treating the body — but manufacturing parts of it.
