We’ve recently been hearing a lot about 3D-bioprinting , a technique in which small body parts can be 3D-printed out of biological tissue. Now, new technology promises to make the process quicker and thus more practical than ever.

 .

Ordinarily, bioprinting is performed in a fashion much like regular 3D printing – an object is slowly built up as successive layers of material are deposited one on top of the other. This means that it can take hours or perhaps days to produce even a simple item.

 .

Lately, though, scientists have been experimenting with a faster method of printing a variety of non-biological objects, which is known as volumetric printing. Working with colleagues at the Netherlands’ Utrecht University, a team from the Swiss EMPA research institute has adapted that technology to produce body parts measuring up to several square […]
