Abstract: In one example, a method of controlling generation apparatus for generating a three-dimensional object is described. For example, data indicative of at least one physical property affecting heat transfer from an object may be determined and used to determine a cooling time, and a component of the generation apparatus may be controlled in response to the determined cooling time.

Abstract: Examples disclosed herein relate to selecting a 3D printing parameter based on voxel property association and conflict resolution. In one implementation, a processor assigns properties to a voxel of a 3D print object based on a first and second zone including the voxel and a condition of a first property associated with the first zone and a condition of a second property associated with the second zone. The processor may update the assigned properties to resolve conflicts between the properties and select a 3D printing parameter based on the assigned properties.

Abstract: According to an example, an arrangement of parts to be printed in a build envelope of a three dimensional (3D) printer may be determined through identification of a plurality of parts to be printed and generation of a respective virtual bounding box for each of the plurality of parts. In one example, a determination may be made that a total volume occupied by the generated virtual bounding boxes falls below a predetermined threshold of the build envelope volume and an arrangement of the virtual bounding boxes inside the build envelope that results in a total height of the virtual bounding boxes being minimized may be determined, to enhance efficiency in printing of the plurality of parts by the 3D printer.

Abstract: In an example, three-dimensional (3D) models of objects are combined for additive manufacturing. Two-dimensional (2D) slices are determined for each 3D model. If the 2D slices are determined to be complete, the 2D slices are combined according to a Boolean operation to generate combined 2D slices printable by an additive manufacturing system.

Abstract: According to one example, there is provided a system for managing the generation of three-dimension objects by an additive manufacturing system. The system comprises a processor to receive one or multiple virtual objects, to generate a spatial arrangement of those objects within a virtual build volume, to control an additive manufacturing system to process the virtual build volume, to modify the virtual build volume in response to a request, and to control the additive manufacturing system to process the modified virtual build volume.

Abstract: The heating of a surface is controlled by: monitoring the temperature of a plurality of zones of the surface to output at least one temperature reading of each of the plurality of zones. The temperature readings are modulated in response to a pattern arranged across a portion of the plurality of zones. The energy delivered to each of the plurality of zones is controlled based on the modulated temperature readings to maintain a substantially homogeneous temperature distribution across the surface.
