3D Chain-mail Structure

Functionally intertwined geometries such as chain mail make it possible to create flexible structures out of hard material. Standard 3D printing does not enables printing of movable structures because supports are required to maintain the shape. Meanwhile, structures can be fabricated inside a gel or liquid monomer by using the multiphoton polymerization technique which makes support‑free 3D printing possible. In this way, movable assembly-free structures can be created. This property opens up the possibility of producing free micromechanical structures that could be used in various fields such as micromechanics and microrobotics.
