In this world full of new developments and advancements in technology, the one thing that people worry most about is health. 3D printing is not just restricted to manufacturing mechanical components but is now being used even in the field of medicine to increase the life span of a person so that we can live a healthy life.3D printing is widely being used in health education, biomedical technology to manufacture prosthetics, or implants that meet the requirements of specific patients. Organs like kidneys, bones, cartilages are printed using biocompatible materials. Since not all materials are biocompatible we have to be selective in choosing the materials for bioprinting since one mistake can cause irreparable damage to the patient. Bio-ink made up of layers of living tissues are used as material for the 3D printers. The biomaterials used should not disturb the haemostasis and should either perform the function of the replaced organ or otherwise support the functioning of the damaged organ without causing any further issues. 3D printing enables the creation of patient-specific organ replicas for medical practices. Custom made prosthetics can be developed so that each patient’s problem can be treated accordingly. In the pharmaceutical industry, tablets are also now being 3D printed.
