1. An additive manufacturing system comprising:
a print box defining a volume having a lateral dimension;
a print carriage movable above the volume, the print carriage defining at least one orifice directed toward the volume as the print carriage moves above the volume;
a roller transverse to the lateral dimension; and
a swing arm including an elongate member having a first end region and a second end region, a first joint disposed along the first end region, and a second joint disposed along the second end region, the elongate member pivotably coupled to the print carriage along a first joint and pivotably coupled to the roller along a second joint, and the swing arm actuatable to pivot the elongate member about the first joint and the second joint to move the roller along a substantially arcuate path relative to the print carriage to position the roller in advance of the print carriage in each direction of bidirectional movement of the print carriage and the roller along the lateral dimension, above the volume.
