Abstract: According to an example, an apparatus may include a processor and a memory. The memory may have stored thereon machine readable instructions that may cause the processor to access an initial halftone image of a three-dimensional (3D) object, the initial halftone image being generated from a continuous tone image of the 3D object. The instructions may also cause the processor to iteratively modify voxel data for the initial halftone image to identify updated voxel data that more accurately corresponds to the continuous tone image than the initial halftone image and to generate halftone image printing data for the 3D object containing the updated voxel data.

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 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: According to an example, a computing apparatus may include a processing device that may access a three-dimensional (3D) object model of a 3D object and determine whether 3D render data for an equivalent 3D object model has previously been processed, is scheduled to be processed, or is currently being processed, the equivalent 3D object model being equivalent to the accessed 3D object model. The processing device may assign 3D render data corresponding to the equivalent 3D object to the 3D object or may generate processed 3D render data for the 3D object using the accessed 3D object model depending upon whether 3D render data for an equivalent 3D object model has previously been processed, is scheduled to be processed, or is currently being processed.

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.
