Abstract

A printed structure including a plurality of overlying layers of elongate polymeric filaments stacked on a surface of a substrate. The elongate polymeric filaments are stacked on each other along their lengths to form a liquid impermeable, self-supporting wall. The liquid impermeable self-supporting wall forms a wall angle of about 30° to about 90° with respect to a plane of the surface of the substrate.
