Eoplex has developed 3D-printing manufacturing techniques for printing sub-micron-size voxels (3D pixels) to mass produce 3D objects. After some simple, but secret, processing, this stuff turns into metal, ceramics, and empty spaces.

The result can be miniature machines with moving parts, metamaterials-enabled multi-function antennas, piezoelectric powered energy harvesters, coin-sized hydrogen fuel cells, pretty much anything.
