State of the art and challenges in bioprinting technologies, contribution of the 3D bioprinting in Tissue Engineering

The rapid growth of the world's population and the increase of human life expectancy has been leading to an increase in demand of organs for transplant. In the search for alternatives to overcome this shortage, Tissue Engineering research is leaning towards biotechnology in order to achieve mass production. Bioprinting is one of the most up-and-coming Tissue Engineering branches on the path to produce viable tissue for implantation, and it will be addressed and discussed in this work. Recent published works in this area have been showing good results, opening doors for a promising future. In the attempt to recreate the research in this area, a bioprinter was built with good resolution and precision for bioprinting testing. The bioprinter was built from ground up, with a simple design and with low cost materials, without compromising its capability.
