In two decades, 3-D printing has grown from a niche manufacturing process to a $2.7-billion industry, responsible for the fabrication of all sorts of things: toys, wristwatches, airplane parts, food. Now scientists are working to apply similar 3-D–printing technology to the field of medicine, accelerating an equally dramatic change. But it’s much different, and much easier, to print with plastic, metal, or chocolate than to print with living cells.
“It’s been a tough slog in some ways, but we’re at a tipping point,” says Dean Kamen, founder of DEKA Research & Development, who holds more than 440 patents, many of them for medical devices.
In labs around the world, bioengineers have begun to print prototype body parts: heart valves, ears, artificial bone, joints, menisci, vascular tubes, and skin grafts.
Three factors are driving the trend: more sophisticated printers, advances in regenerative medicine, and refined CAD software. To print liver tissue at Organovo, Vivian Gorgen, a 25-year-old systems engineer, simply had to click “run program” with a mouse. Honeycomb-shaped liver tissue is a long way from a fully functioning organ, but it is a tangible step in that direction. “Getting to a whole organ-in-a-box that’s plug-and-play and ready to go, I believe that could happen in my lifetime,” says Presnell. “I cannot wait to see what people like Vivian do. The potential is just out of this world.”
