Bioprinting is rapidly becoming a hot trend in the world of medicine. Now a group of Spanish scientists has built a prototype 3D bio-printer that can create a fully functional human skin. The main idea is to build a machine, that can print custom body parts, to transplant them into a patient’s body. Printing custom tissues using a patient’s own body cells would help to eliminate the waiting time and the need for organ donors.
A bioprinter is essentially a 3D printer, but for the body. The printer takes help from the bio-inkin order to create askin. However, bio-ink is not the ink.Instead, it uses cellular components of skin, which include plasma, primary human fibroblast& keratinocytes.Bioink works the same way as the conventional printer ink, and in this case, the bio-links are mixed in such a way that it createsthe human skin. A computer controls the components of the printer that helps to print skin correctly. The printer can print up to 30 square inches of skin per hour, which is much faster than the present skin growing techniques.
The skin looks like a real human skin, which features an external layer for protection just like epidermis, and a thicker layer acts as the dermis. Additionally, it also contains a layer which is made up of fibroblast cells that help to produce a protein named collagen that provides the skin needed elasticity and strength.
