A remarkable breakthrough has been achieved by doctors. As detailed in a recent paper in Science, a team of medical professionals has developed a unique ink that can be 3D printed within the human body. This milestone could enable us to 3D print biomedical devices directly inside the body.

This major development holds potential for numerous medical uses, including repairing broken bones, stopping leaking organs, and more. The foundation of this innovative option lies in the previous invention of photosensitive ink that solidifies when light hits it.

However, light can only penetrate the human body to a certain extent, which is why these doctors decided to use ultrasound sound waves to trigger the ink. This method is known as “deep-penetrating acoustic volumetric printing” (DVAP), and it will enable doctors to 3D print biomedical devices exactly where they’re required.

“Ultrasound waves can penetrate more than 100 times deeper than light while still spatially confined, so we can reach tissues, bones and organs with high spatial precision that haven’t been reachable with light-based printing methods,” the researchers explained in a statement.

Medical advancements like this can open tons of new doors for how doctors treat specific issues. Being able to 3D print biomedical devices directly in the human body will also allow for less intrusive surgery options, depending on the situation.

The bio ink relies on targeted application. Once it reaches its target, though, it is activated by ultrasound waves, allowing to to harden into the pattern and shape that the doctors have designed. There is no information on when 3D printing biomedical devices will be widely available.

Still, this kind of development is astounding and offers an exciting look at how the medical field is advancing. In the past, we’ve also seen scientists and engineers creating magnetically-controlled pill cams that can be driven through the body where they need to go.
