Ever since the advent of modern medicine, organ transplantation surgery has been able to save countless lives of patients whose organs were failing or damaged. However, this technology brought about downsides such as organ sourcing difficulties and the unavoidable immune rejection response.
However, with the introduction of the 3D bio-printer, these issues now have a new technical solution. The 3D bio-printer first feeds in a three-dimensional model built or designed from medical imaging data, dissects the model into numerous layers, and the printer's nozzle layer-by-layer "prints" the "bio ink" composed of biological materials or cells, under the computer's control. This process is continuously repeated until the three-dimensional tissue precursor is printed. After this, the cells start to reorganize and fuse to form new vessels and other tissue structures.
