    Abstract: In an example, a method includes forming a first layer of build material to be processed in object generation and selectively applying at least one print agent on to the first layer based on a print instruction for the first layer. Energy may be applied to the first layer to cause fusion in at least a region thereof, and at least one temperature associated with a thermal contribution of the first layer to a subsequent layer of build material to be processed in object generation may be measured. It may be determined if a temperature condition indicative of a departure from an anticipated thermal contribution of the first layer to a region of subsequent layer exists. If such a temperature condition does exist, a print instruction for applying print agent to the region of the subsequent layer based on the temperature condition may be determined.

    Abstract: In an example, a method of controlling an additive manufacturing apparatus to generate a three dimensional object comprises processing successive layers of build material so as to form successive layers of a three dimensional object, wherein the processing of each layer is performed within a predetermined layer processing time by a plurality of components. The method may further include selecting, by at least one processor, from a plurality of ancillary tasks, at least one ancillary task to be performed in relation to at least one component of the plurality of components. The method may further include scheduling, by at least one processor, the at least one ancillary task to be performed in relation to the at least one component within the predetermined layer processing time for a single layer or for multiple layers of the build material.

    Abstract: A 3D printer is disclosed herein. The 3D printer comprises a build material distributor, an agent delivery device and a controller. The controller obtains slice image data of a sliced virtual build volume including a 3D object to be generated, where the slice image data is indicative, for each slice, of the portions of corresponding build material layers to be solidified. The controller is to determine print data corresponding to each slice, the print data defining a density of printing agent to be applied to regions of each layer based on the slice image data; and to obtain additional data relating to a portion of a slice that corresponds to a sloped portion of the 3D object. The controller is further to modify the determined print data to modify the density of printing agent to be printed at a portion of a given build material layer based on the additional data. The controller is also to control the build material distributor to generate a build material layer; and the agent delivery device to selectively eject the printing agent based on the modified print data.
