Researchers discover how to 3D print ear, nose and knee cartilage

3D printed cartilage

Got arthritis or a sports injury causing joint issues? Doctors may one day be able to 3D-print your problems away.

A team of researchers from Wallenberg Wood Science Center in Sweden have successfully 3D-printed cartilage tissue by developing an ink containing human cells.

It comes down to the ink

The team explains that, previously, printed materials with human cells would collapse, and to they first had to develop an ink containing living human cells that would be able to keep its shape after printing.

In order to create an ink that could hold its shape after bring printed, the researchers mixed used human chondrocytes in, which are cells that build up cartilage.

Once 3D printed, the ink was not only able to hold its shape, but the printed cells were also able to produce cartilage in a laboratory dish.

However, while the team has successfully 3D-printed tissue samples and implanted them into mice, where it has survived and produced cartilage, Gatenholm says further pre-clinical work will need to be done before moving on to human trials.

The research is being presented to the American Chemical Society in San Diego this week.
