3D printing technology is becoming increasingly common in research and industry, but its use is limited due to lack of availability of specialist inks that can be used to generate novel structures. In this study, scientists first made an ink from silicone microbeads, bound in liquid silicone and water. This mixture has a paste-like consistency, similar to household toothpaste, where it can be easily manipulated, but retains its shape and does not drip.

The ink was then fed into a 3D printer and used to create mesh patterns. The final structures are cured in an oven and contain embedded iron carbonyl particles, which allow the researchers to use magnetic fields to manipulate it.
