Abstract
An article of manufacture is disclosed that comprises an infill made from linear segments of filament, such as but not limited to continuous carbon fiber-reinforced thermoplastic filament. Feathering approaches are addressed to generate segments of filament in various geometries that distribute where cuts or ends of segments occur or points where two ends of segments are fused or the like to avoid overlap. Aspects of one approach include identifying long edges and eliminating short edges which present acute angles.
