1. A transport mechanism apparatus forming a periodic nodal surface for transporting at least one of a gas or a liquid, comprising:
an inlet;
an outlet; and
an engineered cellular structure formed in a three dimensional (3D) printing operation to include 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 having openings forming a plurality of flow paths extending in three orthogonal dimensions throughout the transport mechanism apparatus from the inlet to the outlet; and
the engineered cellular structure having wall portions having a mean curvature other than zero.
