3D bioprinting is a very complex process. It first works by taking a small tissue sample from the human its creating the organ or tissue for. This ensures it will be a match and will adapt to the persons body without any issues. Then, like a 3D printer, it makes a model of the organ it is instructed to create. Then, using the sample of tissue, constructs the organ layer by layer. After printed, this organ is put in an incubator in an environment that promotes cell maturation. Then, after sometime where the cells have matured, they fuse to form a living organ. These organs can them be given to people on donor lists.
This is a massive improvement and a big advancement in the health care department that has endless possibilities. First of all, this can help us test diseases and medicine and how they react on human tissue without the risk of harming a human. It can also help reduce testing on animals. We can print skin for people who have skin afflictions from burns, scars, etc. But finally, and maybe the most beneficial part, it can help get people off donor lists quicker, and give organs to those who need it. 3D bioprinting can be the next big thing in healthcare, and help countless people.
