    Abstract: A material management apparatus for an additive manufacturing system comprises a build material supply system to supply build material to a building area for building an object by additive manufacturing. The build material supply system includes a first build material supply unit to supply build material from a first side of a building area and a second build material supply unit to supply build material from a second side of the building area, the second side opposing the first side. The material management apparatus also includes a controller to control the build material supply system to vary an amount of build material to be supplied via the first build material supply unit based on a detected difference between a first amount of material available for supply via the first build material supply unit and a second amount of material available for supply via the second build material supply unit.

    Abstract: A print media support assembly includes a print platen structure having a number of through holes for applying a vacuum from a bottom side to a surface of the print platen structure, and a number of sinkholes in the surface of the print platen structure, each sinkhole associated with at least one through hole for distributing a vacuum, applied via the through holes, across the surface of the print platen structure; the print platen structure supporting a print medium in a print zone; and at least one vacuum belt running across the surface of the print platen structure in a direction of print media advance, the belt overlapping with only part of the surface of the print platen structure to form at least one belt area and at least one non-belt area on the print platen structure; wherein at least one of the density and the size of the through holes and the distribution, the area and the shape of a footprint of the sinkholes is different between the belt area and the non-belt area.
