Abstract: Examples described herein relate to a method of 3D printing. In an example, at least part of a layer of build material is fused. The temperatures of the fused part of the layer are measured at different locations using respective temperature sensors. The temperature sensors are calibrated using the measured temperatures. Heating of additional layers of build material is controlled using the calibrated temperature sensors.

Abstract: A build material management system for a 3D printing system is described in which one or more input ports of a housing of the build material management system is to connect to one or more respective transportable containers. The transportable containers contain a volume of build material comprising 3D printed parts and a portion of non-fused build material. A pump also comprised within the housing is operable to provide a pressure differential across a conduit network of the build material management system. The pump is connected to the input port(s) by the conduit network. An air-flow caused through at least one of the one or more input ports is controlled by processing circuitry also comprised within the housing. The air-flow causes cooling within the respective transportable container. In one alternative, the housing comprises at least two input ports. In all other alternatives, a filling port for filling the or a further transportable container with at least a portion of fresh build material for use in a subsequent 3D printing operation is not comprised within the housing.

Abstract: A method of three-dimensional (3D) printing is provided. Print data is received, which defines patterns of at least one agent to be applied to a layer of build material. These patterns are at least partially based on a 3D model of at least one object to be generated. The print data print data is processed to determine regions which are distant from said patterns. The print data is modified to add a further pattern of a detailing agent to be selectively applied to the layer of build material to generate fracture regions in a processed volume of build material.

Abstract: In an example, a data unit includes a data unit mounting having a circuitry region, a registration portion, and a retaining feature. Circuitry comprising a data source to provide at least one additive manufacturing parameter is arranged on the circuitry region of the mounting. The data unit mounting is to be removably mounted on a receiving portion of an additive manufacturing build material component, such that the registration portion is to be received in a corresponding guide portion of the receiving portion of the additive manufacturing build material component, and the retaining feature is prevent removal of the data unit from the receiving portion unless deformed. Deformation of the retaining feature to effect removal of the data unit from the receiving portion may be a permanent deformation.

Abstract: Examples of an inlet to enable a forced air flow to enter a build material container in a 3D additive manufacturing system are described. In one case, the inlet has a structure having an inner face and an outer face forming at least one aperture through the structure through which forced air flows in use. The inlet has a longitudinal axis and the inner face and outer face are non-aligned along at least one axis which passes through each of inner face and the outer face and is substantially parallel to the longitudinal axis.
