Biofabrication of Vascularized Tissues Using Sacrificial Bioprinting

Quick fact

The 'sacrificial' ink used in this technique can be as simple as a sugar solution or a special gelatin—designed to be printed, then washed away with a gentle flow of fluid or a change in temperature, leaving behind a perfect network of hollow tubes.

Why this is interesting

Imagine trying to grow a piece of human tissue thicker than a sheet of paper, only to have it die from the inside out. Sacrificial bioprinting might just be the key to keeping it alive—by building it with vanishing blood vessels.
