Medical researchers have been able to create certain kinds of living cells with 3D printers for more than a decade. Now a few companies are getting closer to mass production of higher-order tissues (bone, cartilage, organs) and other individually tailored items, including implants. This kind of precision medicine, treating patients based on their genes, environment, and lifestyle, could herald the end of long organ donor lists and solve other problems, too.
