The material was made in a single steel sheet using lasers to engrave «chiral,» or geometric
microstructure patterns, which are asymmetrical to their mirror images (see photo).

In addition to making batteries, he says, the 3D
patterning technique is likely to be useful for making a wide variety of novel carbon - based
microstructures.
To achieve this, the team used an off - the - shelf digital micromirror array from a commercial video projector to create a set of
microstructured light
patterns that are sequentially superimposed onto a sample.
By combining scanning electron microscopy with x-ray computer tomography to examine the bead's
microstructure and chemistry, a British research team determined that the iron possessed a structural and microchemical signature known as the Widmanstätten
pattern that is unique to weathered iron meteorites.
Because we're printing something that already contains a specific
microstructure, we don't have to
pattern each individual piece.
«Foam inks are interesting because you can digitally
pattern cellular
microstructures within larger cellular macrostructures,» said Joseph Muth, a graduate student in the Lewis Lab and first author of the paper.
The
Microstructures series is conceptually based on 3D gradient
patterning and explores the use of pioneering 3D printing technology at the scale of furniture.
