Review on 3d Printing of Biological Tissues and the Materialization

Abstract

3D printing is one of the recently evolved manufacturing techniques which has wide range of applications in engineering, education, art and science. Bioprinting is the recent advancement of additive manufacturing process in the area of medicine. It is a process which involves layering and curing of biological cells or tissues and turning it into a fully functioning organ or hard supports(bones). It has solved the problem of shortage of organs for transplantation. It would be very difficult to find the right organ according to the needs of a particular person but this recent advancement has given a right solution for it. Bioprinters typically uses bioinks which dispenses through the nozzle of the printer for deposition, and a dissolvable hydrogel is used in order to protect and support the tissues of the organic material. This type of printing is done in lab environment only under a controlled system.
