Can 3D printing be used in the field of medical science?

Yes, Medicine is one of the first and foremost applications of 3D printing. It has brought a  wave in the field of the healthcare industry. From kidneys to hands are 3D printed using stem cells of the patient? 3D printing is playing a crucial role in the medical ecosystem by printing artificial organs which are meant to replace or enhance human machinery. 3D printing has become a revolutionizing industry in hundreds of areas like commercial products and engineering. However, the development has been especially notable in the biomedical field.

It is being used to make prosthetic limbs, replacements for bones, tendons, and other functional organ pieces, as well as living human tissue for the testing and development of new drugs. It is a major breakthrough as 3D printing industry has evolved and has begun to print human faces too. 3D printing technology successes in the medical industry include the creation of limb prosthetics, titanium replacements for hips & jaws and plastic tracheal splints etc.

The primary purpose of printable organs is in transplantation. Research is currently being conducted on the artificial heart, kidney, and liver structures, as well as other major organs. For more complicated organs, such as the heart, heart valves have also been the subject of research. Some printed organs have already reached clinical implementation, and primarily include hollow structures such as the bladder, as well as vascular structures such as urine tubes.

3D is used to create scaffolding structures that less tenacious tissue can grow onto in the process of creating grafts and other surgical appurtenances.

Let us have a closer look at organ printing. 3D printing allows for the layer-by-layer construction of a particular organ structure to form a cell scaffold. This can be followed by the process of cell seeding, in which cells of interest are pipetted directly onto the scaffold structure. Additionally, the process of integrating cells into the printable material itself is done.

How It Works.?

Modified inkjet printers have been used to produce three-dimensional biological tissue. Printer cartridges are filled with a suspension of living cells and a smart gel, the latter used for providing structure. Alternating patterns of the smart gel and living cells are printed using a standard print nozzle, with cells eventually fusing together to form tissue. When completed, the gel is cooled and washed away, leaving behind only live cells.

3D printing has changed the lives of many by giving back their strengths and happiness. In India,3D printed spine has saved a life of a woman from paralysis.

The likelihood of 3D printing functional organs just took a huge step forward, with scientists at the University of California working out a way to print not just the organ, but also the blood vessels needed to transport nutrients, oxygen and metabolic waste. Degenerative joint diseases like arthritis affect millions of people around the world, and range in severity from somewhat annoying to severely debilitating.

While scientists have been trying for decades to create cartilage in the lab, it’s proved to be difficult. Especially when it comes to the complex, load-bearing cartilage in the knee. So it’s quite a breakthrough that Indian researchers have managed to develop cartilage.  That is molecularly similar to that in the knee, using 3D bioprinting.

Future scope

Though 3D printing remains expensive, slow and complicated process, it has reached greater heights because of its accuracy and precision.  3D printers are perfected year by year, leading to more applications of 3D printing. It is contributing greatly to commerce, engineering, and especially biomedical field. 3D printing has saved many lives through transplantation of organs. 3D printing has ocean of applications.
