Scientists Successfully 3D Print an Organ That Mimics Lungs

In a 3D printing first, scientists have figured out how to print artificial versions of the body’s complex vascular networks, which mimic our natural passageways for blood, air, lymph, and other vital fluids.

“One of the biggest road blocks to generating functional tissue replacements has been our inability to print the complex vasculature that can supply nutrients to densely populated tissues,” says Jordan Miller, assistant professor of bioengineering at Rice’s Brown School of Engineering, who helped lead the team, in a press statement.
