Every day in the U.S., about 22 people die waiting for an organ transplant. If scientists could 3-D print organs like kidneys, livers and hearts, all those lives could be saved. For years, people have been touting personalized organ printing as the future.

But despite decades of promising work in bioengineered bladders and other kinds of human tissue, we’re not close to having more complicated organs made from scratch. Harvard professor Jennifer Lewis, a leader in advanced 3-D printing of biological tissue, has only recently developed the ability to print part of a nephron, an individual unit of a kidney.

I asked Lewis what it will take to someday print a full kidney or a similarly complex organ.

Gel scaffold paves way for 3D printing of biological organs

3D printing needle creates intricate objects in soft gels

To improve 3D printing, simply add gel. A fresh technique uses one to support complex shapes that would fall apart under their own weight in normal 3D printing.

This new-found combination of strength and delicacy will be crucial if we’re ever to print the biological structures that make up organs, blood vessels and other tissue.
