Abstract: Certain examples relate to generating output print data representing at least one object. Output print data is generated by performing a geometric transformation on a part of object model data representing the identified region. The object model data represents the at least one object to be printed. The geometric transformation may use a transformation parameter which is determined based at least on the object model data and object property data. The object property data identifies a region of the at least one object and associates it with a selected physical property.

Abstract: In an example, a method includes receiving, at least one processor, voxelised object model data describing at least part of an intended fabrication chamber content to be generated using additive manufacturing. The voxelised object model data may be derived from a first data set modelling a first object as 2D slices and a second data set modelling a second object as a 3D mesh. Data within the voxelised object model data which is derived from the first data set may be identified, and a geometrical transformation may be applied thereto.

Abstract: In an example, a method includes receiving, by at least one processor, object model data representing at least a portion of a first object that is to be generated by an additive manufacturing apparatus. An indication of a proportion of the first object which is solid may be determined, and, based thereon, a dimensional compensation value may be determined. The determined dimensional compensation value may be applied to the object model data to determine modified object model data.

Abstract: In certain examples, a method comprises determining a fusing area density distribution of a build layer from build data relating to a build layer of a three-dimensional model to be printed by an additive manufacturing system. The method comprises, in response to a determination that a region of the build layer has a fusing area density outside of a fusing area density tolerance window, modifying the build layer to define a build layer in which the region has a fusing area density that is within the fusing area density tolerance window.

Abstract: In an example, a tangible machine-readable medium stores instructions which, when executed by a processor, cause the processor to evaluate a plurality of possible object generation arrangements based on a default separation distance and an enhanced separation distance, wherein the enhanced separation distance is used to assess predefined object sub-portions.

Abstract: In an example, a method includes generating a training dataset for an inference model to generate dimensional modifications to apply to object models to compensate for departures from model dimensions in objects generated using additive manufacturing based on those object models. Generating the training dataset may include acquiring, for each of a plurality of generated objects, (i) an indication of a first dimensional inaccuracy and a second dimensional inaccuracy, wherein the first and second dimensional inaccuracies are acquired in a direction of a first axis and relate to respective first and second object dimensions; and (ii) an indication of object placement within a fabrication chamber during object generation.

Abstract: In an example, a method includes receiving, at least one processor, object model data representing at least a portion of an object that is to be generated by an additive manufacturing apparatus by fusing build material within a fabrication chamber. An intended object placement location within the fabrication chamber may be determined, and a dimensional compensation to apply to the object model data may be determined using a mapping resource relating dimensional compensations to object placement locations. The determined dimensional compensation may be applied to the object model data to generate modified object model data using at least one processor.

Abstract: A computer-implemented method is disclosed. The computer-implemented method comprises receiving data indicative of a post-manufacture treatment to be applied to a three-dimensional object following completion of a manufacturing process to generate the three-dimensional object; and determining, based on the received data indicative of the post-manufacture treatment, build parameters to be applied in respect of the manufacturing process. A manufacturing apparatus and a machine-readable medium are also disclosed.

Abstract: In an example, a method includes obtaining an indication of a deviation from an expected dimension of at least one dimension of an object generated using an additive manufacturing apparatus. A geometrical compensation model to apply to object model data for generating objects using additive manufacturing to compensate for anticipated deviations in dimensions may be determined from the obtained indication. The geometrical compensation model may comprise a first value to apply to object model data to modify a specification of an external dimension; and a second, different, value to apply to object model data to modify a specification of an internal dimension.
