Can 3D printers print medical biological tissue materials?

British researchers published a report in the "Science" magazine that they used a special 3D printer to print out materials similar to biological tissues. This result is expected to be applied in the medical field in the future.

This report was jointly published by Professor Hegen Bailey of Oxford University and colleagues. According to reports, they used a 3D printer to eject a large number of droplets wrapped in a lipid film in layers, and these droplets formed a network structure to form a special new material.

The researchers say that the material printed in this way is similar in texture to the brain and adipose tissue, can perform folding actions similar to muscle-like activities, and has a communication network structure that works like neurons, and can be used to repair or enhance failed organs. Since this is a synthetic material, it can also avoid some of the problems caused by stem cells and other methods of making living tissue.

The researchers also said that conventional 3D printers cannot print this new material. In the experiment, they used a special 3D printer. At present, the diameter of the droplets ejected by this printer is about 50 microns, which is as large as 5 living cells. But I believe that the droplet size can be reduced in the future.
