    Abstract: An apparatus has a processor and a machine-readable storage medium storing machine-readable instructions executable by the processor. The machine- readable instructions cause the processor to, upon obtaining an indication that a calibration of a 3D printing machine is to be performed, arrange user calibration objects to be printed and calibration objects to be printed and to be used in the calibration in a virtual build volume. Arranging calibration objects in the virtual build volume comprises arranging the calibration objects at print job specific locations reserved for calibration objects and/or replacing user objects with calibration objects.

    Abstract: In an example, a method includes receiving, at a processor, an object model describing a geometry of a three-dimensional object, and determining a transformed data model describing a volume containing a modified version of the three-dimensional object as a plurality of categorised contiguous, non-overlapping sub-volumes, wherein the modified version of the three-dimensional object includes a surface offset. Determining the transformed data model may comprises categorising the sub-volumes by defining a first region by determining an area swept by an offset operator when the offset operator is swept around a boundary of the sub-volume and defining a second region, interior to the first region, and indicative of the closest approach of the offset operator to the sub-volume when the offset operator is swept around the boundary. Intersections between a surface of the object model and at least one of the first and second region may be determined. When the surface intersects the second region, the sub-volume may be categorised as interior to the three-dimensional object; and when the surface intersects the first region and not the second region, the sub-volume may categorised as spanning a boundary of the three-dimensional object.

    Abstract: In an example, a method includes receiving, at 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, wherein the object model data comprises a mesh model comprising data describing a surface of the object. A geometrical compensation vector may be determined for the object model data, the geometrical compensation vector having a first component applying to a first axis of the fabrication chamber and a second component applying to a second axis of the fabrication chamber. A geometrical compensation to apply to at least one location on the surface of the object may be determined by determining a product of the geometrical compensation vector and a vector indicative of the normal of the object surface at the location and the determined geometrical compensation may be applied to the object model data to generate modified object model data.

    Abstract: In an example, a method includes receiving, at 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 indication of an intended object placement location within the fabrication chamber may be determined, and a plurality of predefined locations within a fabrication chamber may be identified based on a volumetric extent of the object or object portion if placed in its intended object placement location, wherein the predefined locations are related to dimensional compensation values. A dimensional compensation value to apply to the object model data may be determined by combining the dimensional compensation values relating to the identified plurality of predefined locations and applied to the object model data to generate modified object model data.

    Abstract: Certain examples described herein relate to a removable unit for a three dimensional printing system. The removable unit comprises at least one compartment to store build material for a three-dimensional print job, a coupling to engage with a printer device of the three-dimensional printing system, and a memory. The memory is configured to store instructions for the three-dimensional print job for the printer device, and the instructions are readable from the memory by the printer device when the removable unit is engaged with the printer device.

    Abstract: In an example, a method includes determining a training dataset for an inference model to evaluate spatial arrangements of objects to be generated in additive manufacturing. Determining the training dataset may include obtaining, by at least one processor, a temperature distribution for each of a plurality of spatial arrangements of objects to be generated in additive manufacturing. The method may further include obtaining, using at least one processor, an indication of thermal interaction for each spatial arrangement based on the obtained temperature distribution.
