3D-Printed Organ Capable of “Breathing”

Bioengineers at Rice University and the University of Washington crafted a first-ever 3D-printed “breathing” organ. Developing an organ that can maintain (aka breathe and transmit oxygen) has proven to be the most difficult part of the research: growing living cells is simple, researchers argue, but keeping them alive is much more difficult. This lung is 3D-printed from soft gels which allow it to expand and contract, and a complex network of vascular networks built from the same material allows for the transmission of oxygen to connected blood vessels.
