3D printed lung-mimicking ‘air sac’ brings functioning bioprinted organs a step closer

A new 3D-printed model of a lung-mimicking air sac has been created, complete with functioning airways that are capable of delivering oxygen to surrounding blood vessels. It was made by a team of researchers in the US by gradually building up layers of hydrogel, a synthetic, jelly-like material that shares many features in common with human tissue.

The same technique could be used for creating complex, entangled vascular networks that mimic the body’s natural passageways for blood, and other vital fluids, potentially opening up a new means of bioprinting human organs for transplant, they say.
