ABSTRACT:
Known fabrication apparatuses, including patterned pinch rollers, molds, etc., are adapted to create articles having a shape characterized by more than six faces of identical size and shape, and by members extending outwardly in three orthogonal dimensions, the articles each including at least a pair of faces which intersect to bound a concave region, each article including a plurality of such concave regions. In certain embodiments, vibrational energy (e.g. ultrasonic or microwave energy) is utilized to aid in article formation.
