3D bioprinting is a laboratory-based cousin of 3D printing that prints cells and biomaterials instead of plastics and metals. Like ordinary 3D printers, bioprinters have computer-controlled printheads that can deposit biomaterials (or “bio-inks”), usually via extrusion or drop-on-demand placement.

The sensitive nature of these materials limits the scope of possible three-dimensional shapes. That said, bioprinting is one of the most important and potentially significant forms of 3D printing, since researchers are using bioprinters to develop artificial human organs from living cells.
