3D Printing of Body Parts Is Coming Fast—but Regulations Are Not Ready

In the last few years, the use of 3D printing has exploded in medicine. Engineers and medical professionals now routinely 3D print prosthetic hands and surgical tools. But 3D printing has only just begun to transform the field.

Today, a quickly emerging set of technologies known as bioprinting is poised to push the boundaries further. Bioprinting uses 3D printers and techniques to fabricate the three-dimensional structures of biological materials, from cells to biochemicals, through precise layer-by-layer positioning. The ultimate goal is to replicate functioning tissue and material, such as organs, which can then be transplanted into human beings.

We have been mapping the adoption of 3D printing technologies in the field of health care, and particularly bioprinting, in a collaboration between the law schools of Bournemouth University in the United Kingdom and Saint Louis University in the United States. While the future looks promising from a technical and scientific perspective, it’s far from clear how bioprinting and its products will be regulated. Such uncertainty can be problematic for manufacturers and patients alike, and could prevent bioprinting from living up to its promise.
