Abstract: According to one example, there is provided an accessory for a three-dimensional (3D) printer. The accessory comprises an upper structure to connect to a 3D printer build unit, the build unit defining a build chamber and having a movable support platform, the upper structure defining a build chamber smaller than the build chamber of the build unit, the upper structure being connectable to the build unit such that the accessory build chamber becomes the usable build chamber of the build unit, and an accessory support platform movable within the accessory build chamber, the accessory support platform having a base portion extending below the accessory build chamber to connect to the build unit support platform, such that movement of the build unit support platform causes corresponding movement of the accessory support platform.

Abstract: A 3D printing apparatus is disclosed herein. The 3D printing apparatus comprises a build compartment defining a build chamber within which a 3D object is to be generated; and a non-powered platform, moveable within the build chamber, comprising a platform drive interface to engage with an external drive mechanism to cause the platform to move. The 3D printing apparatus further comprises a powder compartment located laterally adjacent to the build compartment, within which build material is to be stored for use in the generation of the 3D object. The 3D printing apparatus also comprises a locking interface to couple the 3D printing apparatus with an external hosting device.

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.
