The First Universal Bioink for Living Tissue Printing Test Printed Miniature Ears

Paige Anne Carter



3D printing technology has made it possible for people to create human organs in reality. There are now many 3D printing companies that have invested in technology to improve the field of medical technology. One such company is CELLINK which created a universal bioink aimed at printing live and functional human tissue models.

Each day, more than 20 patients die while waiting for an organ transplant. With the revolutionary bioink from CELLINK, it is possible to manufacture “donor” organs artificially. However, in order to create functional organs, it is important for researchers to use a biocompatible substance to print successful organs.

The problem with most bioprinters is that they have different set-ups and configurations thus using a universal bioink can be a problem. Current bioprinters work in such a way that it needs two extruders for laying the bioink and laying the cells to the ink. Conventional bioinks serve as the substrates for the cells to grow onto.

However, the bioink developed by CELLINK is basically a special type of living ink that is made available for a wide range of 3D bioprinters. The cells and the bioink are mixed together thus only a single nozzle is required to create the organ. It is s a stand-alone product that can be used to revolutionize experimental cell culturing using 3D printing technology. To test the efficacy of the bioink, CELLINK first tested the new product by printing miniature ears. However, they are looking on ways to expand the technology to be able to print more organs.
