Introduction
In today’s world, technology plays an important role in every industry as well in our personal lives. Out of all the industries, healthcare is definitely one of the most important. Technology in the medical field has had many positive impacts on society today. People are living longer, curing diseases that were once thought to be impossible to cure and improving our daily lives. Areas like biotechnology, pharmaceuticals, the development of medical devices and equipment, and more, have all made important contributions to improve the health of people all around the world. Technology has made a significant impact on medicine from small innovations like bandages, to larger technologies like 3D Bioprinting. The term of 3D Bioprinting is the process and “production of biological entities, such as tissues and organs” (3D Printing, 2014). Through this process cells are preserved to regenerate human tissues, which are created by human cells. It would be a dream come true for many patients awaiting donor organs, if a lost organ can be replaced or a scar on a pretty face can be eliminated with a fresh layer of tissue.

Research- 3D Bioprinting Technology
What is the basic principle of Bioprinting?
Bioprinting helps to replicate human organs for transplant. The technology involves the creation of replacement tissues and organs that are printed layer-by-layer into a three dimensional structure. The parts are made from the organ recipient’s own genetic matter, and precisely match the tissue or organ they replace. The printer allows researchers to place cells into a 3D pattern and works by using a robot to lay down these cells in precise 3D position (Conner, 2010). A printer cartridge is moved back and forth on a petri dish. A liquid is kept in the petri dish and the cartridges have cells inside them instead of ink. Inside, it has a cross linker for binding, and this cross linker turns the liquid into a gel like substance over which the cells are deposited. The process is repeated with addition of liquid and more layers of cells. In this way, cells are structured for the formation of an organ (Seliktar D., Dikovsky, D. , & Napadensky, E., 2013).

Who are the pioneers in Bioprinting?
Organovo Holdings, Inc. was one of the pioneer companies designing and creating functional human tissues using Bioprinting technology. Their goal is to build and produce three- dimensional human tissues for medical research and therapeutic applications. The company developed one of the world first 3D bio printers that can create fully functional human tissues, including blood vessels, lung, liver and kidney tissues, nerve guides and cardiac sheets and patches. Between 2004 and 2005 they begun the organ printing at University of Missouri. In 2013 they establish collaboration for cancer research and in January 2014 they announce the delivery of the first 3D liver tissue. (Changing the Shape of Medical Research and Practice, 2013-2014). The company is collaborating with pharmaceutical partners to develop human biological diseases models in three dimensions. These human tissues have the potential to accelerate drug discovery process, enabling treatments to be developed faster and at lower cost.

Conclusion
It was a learning experience researching about such fascinating topic. Improving quality of life is one of the main benefits of integrating new innovations into medicine. There are still limitations to this technology but research is being carried out and there is a strong future for Bioprinting. Through this research I have learned some of the uses of...
