Additive manufacturing system and method

An additive manufacturing system comprising:

• a print system configured to extrude an additive material towards an end-piece, the print system including a first nozzle having a plurality of orifices, the plurality of orifices including at least a first orifice and a second orifice, the first orifice both laterally and vertically offset from the second orifice, the print system further including an adjustment actuator configured to alter a position of the first nozzle relative to the endpiece;
• a compressor unit within a working envelope of the print system and remote from the adjustment actuator, wherein the first nozzle is movable via the adjustment actuator relative to the compressor unit;
• and
• a computing system including one or more processors and one or more non-transitory computer-readable media that collectively store instructions that, when executed by the one or more processors, configure the computing system to:
• determine an end-piece path through actuation of an articulation system based on a defined design of an article;
• control the print system to extrude the additive material from the print system during a first additive process, wherein the first additive process comprises extruding multiple filaments of the additive material simultaneously through the first nozzle along a common pass of the end-piece along the first nozzle, wherein the multiple filaments are extruded with varied thicknesses relative to one another and the adjustment actuator dynamically varies a distance of the first nozzle from the end-piece during the common pass to create air pockets within the additive material between the multiple filaments;
• and
• control the print system to move the end-piece between the first nozzle and the compressor unit configured to compress the additive material to alter a characteristic of the additive material.
