Abstract: A 3D printing system comprising: a selective solidification module to: form a printed article by processing a build material; and form a printed container encompassing the printed article and a portion of unused build material about the printed article, the printed container defining a first port and a second port fluidly connected to the first port. The 3D printing system further comprises a connector to couple to the first port or second port of the printed container; and a pump fluidly connected to the connector to cause a fluid to flow through the printed container from the first port to the second port such that the printed article is cooled by the fluid flow.

Abstract: Certain examples described herein relate to a removable unit of an additive manufacturing system. The removable unit is connectable to a base unit. When connected and operational, the base unit supplies a first voltage to the removable unit via a first power coupling. The removable unit has a power supply unit that converts the first voltage to a second voltage. The second voltage may power a number of low voltage components. The removable unit also has a power multiplexer. When the first voltage is unavailable the removable unit switches the power multiplexer to use a second voltage that is supplied from the base unit via a second power coupling.

Abstract: In example implementations, an apparatus includes a storage unit, an auger screw, a housing enclosing the auger screw and at least one heater coupled to the housing. The auger screw receives a build material from the storage unit and delivers the build material to a build platform via movement of the auger screw. The build material is heated by the at least one heater as the build material is being moved by the auger screw.

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: In example implementations, an apparatus includes an interface. The interface is to detect a connection to a 3D printer and a connection to a powder supply/post-processing component. The interface may be in communication with a processor. The processor may also be in communication with a timer. The timer is to begin tracking a cooling time when the interface is disconnected from the 3D printer and the processor is to transmit the cooling time to the powder supply/post-processing component when the interface detects the connection to the powder supply/post-processing component.
