Abstract: An additive manufacturing system has a controller configured to modify numerical control programming instructions to form interlocking structures that improve object structural integrity in the Z-direction. The interlocking structures are produced by forming one layer with swaths that are separated by gaps and another layer that is formed over the gaps to fill the gaps and lay over the swaths forming the gaps.

Abstract: An additive manufacturing system has a controller configured to operate an actuator to move a multi-nozzle extruder in an XY plane and rotate the multi-nozzle extruder about an axis perpendicular to the XY plane while operating the multi-nozzle extruder to form swaths in the XY plane. The controller operates the actuator and the multi-nozzle extruder to keep the nozzles of the extruder within perimeters formed for an object and to vary the speed and rotation of the extruder while extruding material to form precise structures.
