Abstract

According to one aspect, embodiments of the invention provide an additively manufactured part, comprising a top portion, a bottom portion, and a plurality of compacted composite filaments arranged in layers between the top portion and the bottom portion, each compacted composite filament including one or more axial fiber strands, wherein the plurality of compacted composite filaments includes a first compacted composite filament located in a first layer and a second compacted composite filament located in a second layer, the first layer being located closer to the bottom portion than the second layer, and wherein the second compacted composite filament layer is compressed against the first compacted composite filament, forming a vertically bonded rank in which the one or more axial fiber strands of the second compacted composite filament intrudes into the first compacted composite filament.
