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.
Claims19
An apparatus for producing shaped articles comprising:
- feed means for introducing a feed material from which said articles are to be shaped;
- and
- shaping means for receiving said introduced feed material and for shaping same, said shaping means including a pair of patterned members;
- the patterns on said members being shaped to produce articles whose geometry is characterized by more than six faces of identical size and shape, and by members extending outwardly in three dimensions, said articles each including a plurality of faces, at least a pair of which intersect to bound a concave region, each article including a plurality of such concave regions.
