1. A method for forming a transport mechanism for transporting at least one of a gas or a liquid, comprising:
using a three dimensional (3D) printing operation to form the mechanism with an inlet and an outlet;
controlling the 3D printing operation to create the mechanism as an engineered surface structure formed in a layer-by-layer process using the 3D printing operation; and
further controlling the 3D printing operation such that the engineered surface structure includes a plurality of cells propagating periodically in three dimensions, with non-intersecting, non-flat, continuously curving wall portions which form two non-intersecting domains, and where the wall portions have openings forming a plurality of flow paths extending in three orthogonal dimensions throughout the transport mechanism from the inlet to the outlet, and such that the engineered surface structure has wall portions having a mean curvature other than zero.
