Abstract: Examples relate to methods of printing a 3D printed tamper evident security structure for protecting a feature; the method comprising repeatedly: depositing a layer of build material; doping one or more than one region of the layer of build material using a dopant to influence a respective electrical attribute of one or more than one region associated with a graph of the structure; and agglomerating one or more than one selected portion of the layer of the build material, including the one or more than one doped region of the layer of build material, to form progressively the graph with a predetermined measurable electrical characteristic.

Abstract: According to one aspect, there is provided a management system to control a 3D printing system that includes at least one 3D printer, at least one build unit in which 3D objects can be generated by the 3D printer, and at least one material processing unit in which processing operations can be performed on the build unit. The management system comprises a processor to obtain status data from at least some of the elements of the 3D printing system, to obtain data relating to a print job to be printed, to determine, from the obtained data, a schedule of operations to be performed by elements of the 3D printing system and to generate control data to allow enforcement of the determined schedule.

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: A printer comprising an electrical load, a control system and an electrical circuit to switchably connect the electrical load to a first phase and a second phase of a polyphase power supply. The control system monitors a first electrical current drawn by the printer on the first phase and a second electrical current drawn by the printer on the second phase. When a difference between the first electrical current and the second electrical current satisfies a threshold condition, the control system controls the electrical circuit to disconnect the electrical load from the first phase and connect the electrical load to the second phase.

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: A method, control circuit and printing system to control data communications with a plurality of integrated circuits. The method comprises receiving a control signal indicating that a first integrated circuit in the plurality of integrated circuits has been connected to an interface; pausing data communication between a processor and a second integrated circuit in the plurality of circuits over a data bus; and sending an enable signal to transition a switch from an open state to a closed state to connect a power supply to the interface while data communication with the plurality of integrated circuits over the data bus is paused.

Abstract: A build material container (100) may comprise a container body (102) enclosing a volume to contain a build material (104) for three-dimensional printing. In an example, the container body comprises a sidewall. A compressible wall element (108) may be disposed in the sidewall, wherein compression of the compressible portion wall element reduces the volume of the container. An opening (112) to introduce the build material into the container body may be disposed in an upper region of the sidewall.
