The ability to one day print organs is what medical 3D printing industry is after. However, it’ll still be a while for that to become a reality. Human vasculature is incredibly complex and difficult to print accurately, but a team from the Lawrence Livermore National Library (LLNL) seem to have found a way to 3D print blood vessels.

The California-based team used special 3D bioprinters to print an initial structure out of cells and other organic materials and then to augment it using ‘bio-ink’ – a material designed to be compatible with living human tissue.

As the video above shows, the researches printed two small blood vessels out of [...]
