New bio-ink for 3D printing

Scientists have found a new bio-ink for 3D printing with stem cells that allows printing of living tissue known as bio-printing. The new bio-ink contains two different polymer components: a natural polymer extracted from seaweed and a sacrificial synthetic polymer used in the medical industry. “Designing the new bio-ink was extremely challenging. You need a material that is printable, strong enough to maintain its shape when immersed in nutrients and is not harmful to the cells. We managed to do this,” said researcher Adam Perriman from school of cellular and molecular medicine.
