The technology is in its infancy, yet bioengineers are creating human tissue through computerized adaptive manufacturing, or 3-D printing right now. Today.
A Wall Street Journal article, Printing Evolves, An Inkjet for Living Tissue, has details.
Scientists can build tissue, such as a blood vessel, one dot of tissue at a time, just like other 3-D printing applications. Around the tissue a separate nozzle places a water-soluble gel, called hydrogel, that works like a mold to hold the tissue in place until the dots of tissue knit together. After the printing is done, the tissue is stored in a solution that provides nutrients. Then after a few weeks to stabilize, the hydrogel is washed away.
