Abstract: Certain examples described herein relate to build units that are physically connectable to at least one host apparatus of an additive manufacturing system. A build unit comprises at least one controllable device useable in an object building operation. In certain examples, the at least one device is controllable according to first control instructions originating from the at least one host apparatus when the build unit is physically connected to the at least one host apparatus. In certain examples, the at least one device is also controllable according to second control instructions generated independently of the at least one host apparatus when the build unit is not physically connected to the at least one host apparatus.

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.
