ABSTRACT:
A nozzle for extruding a surface may include a first outlet configured to controllably extrude a first extrudate of unhardened material, a second outlet configured to controllably extrude a second extrudate of unhardened material that is separated from the first extrudate, a third outlet configured to extrude a third extrudate of unhardened material between the first and the second extrudates, and a controller. The third outlet may have a width that is substantially less than the distance between the first and second extrudates. The controller may be configured to cause the third extrudate to repeatedly traverse between the first and second extrudates and/or to cause the third extrudate to leave a plurality of substantial and separated spaces between the first and second extrudates.
