Abstract: According to one example, there is provided a non-transitory computer-readable medium on which is stored computer-readable instructions that when executed by the computer cause the computer to obtain data relating to a set of objects generated by an object generation system, display using the obtained data a visualization of the set of objects, receive user input identifying a set of objects displayed in the visualization, supply, based on set of identified objects, obtained data, or data derived therefrom, to a post-processing module that is to process a set of objects corresponding to the set of identified objects.

Abstract: Information on assembly components to be printed by a three dimensional (3D) printer is accessed. Different assembly arrangements are determined based on the information to optimise three dimensional (3D) nesting.

Abstract: In an example a method comprises receiving at a processor, a digital model representing an object to be produced by additive manufacturing. The method may comprise receiving, at the processor, a selected location on a surface of the object, where a label is to be formed. The method may further comprise defining a label displacement map associated with the selected location, applying the label displacement map to the digital model, and rendering the digital model including the label displacement map into voxels for additive manufacturing.

Abstract: According to examples, a processor may dilate a first digital model of a first 3D part a predefined amount and a second digital model of a second 3D part the predefined amount, in which the first 3D part and the second 3D part are to be fabricated together in an assembly to have a functional relationship with respect to each other, and in which the first digital model and the second digital model are spaced from each other in a manner that corresponds to a spacing of the first 3D part and the second 3D part in the assembly. The processor may determine a spatial relationship between the dilated first digital model and the dilated second digital model and may determine, based on the determined spatial relationship, whether the assembly of the first 3D part and the second 3D part is predicted to function properly when the assembly is fabricated.
