3D Printer Makes World’s Smallest Human ‘Livers.’

3D printing technology just keeps getting better and better. This time, scientists at Organovo in San Diego were able to create a 3D printer that prints using liver cells. Layering these cells into a histologically correct lattice, the team plans to model disease processes and medication effects more accurately.

The plan is to eventually be able to print fully functional human livers that are viable for transplantation.

Nothing to fear inside.
