Scientists have presented an organ that could be created using traditional printing methods.
“The technology that we have developed is 10-50 timesfaster than the industry standard, and it works with large samples that were previously difficult to manufacture, ”said study co-author Ruogang Zhao. They published the study in the journal Advanced Healthcare Materials.

The method is based on hydrogels, whichused to create diapers, contact lenses and tissue engineering materials. The latter application is especially useful in 3D printing, and it is on this that the research team has spent most of their efforts optimizing them for fast and accurate 3D printing techniques.
“Our method allows you to quickly print hydrogelmodels in centimeter size. It significantly reduces deformation of parts and damage to cells caused by prolonged exposure to the environment, which is usually seen with conventional 3D printing methods, ”notes another co-author of the study, Chi Zhou.
Researchers say that this method is especiallysuitable for printing cells with embedded blood vessel networks, an emerging technology that will become a central part of the production of human tissues and organs using 3D printing.
