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: 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 examples, a processor may identify locations on a digital 3D model of an object corresponding to positions at which features are to be added to the object. For each of a plurality of locations of the identified locations, the processor may identify displacements of each of a plurality of patch points around the location from the surface of the digital 3D model. The processor may also create a map of the digital 3D model that encodes the identified displacements of the patch points around the locations, in which a 3D fabrication system is to fabricate the object to include the plurality of features based on the digital 3D model and the created map.

Abstract: Examples of methods are described herein. In some examples, a method includes determining a graph representation of a three-dimensional (3D) object based on a voxel representation of the 3D object. In some examples, the graph representation includes nodes corresponding to voxels of the voxel representation and edges associated with the nodes. In some examples, the method includes predicting, using a machine learning model, a sintering state of the 3D object based on the graph representation.

Abstract: Examples of design element placement on 3D surfaces are described herein. In some examples, a three-dimensional (3D) mesh of a 3D surface is converted to a two-dimensional (2D) surface. In some examples, placement of design elements on the 2D surface is determined to maximize density of the design elements while satisfying a minimum separation distance between the design elements. In some examples, the design element placement on the 2D surface is converted to the 3D surface.

Abstract: An example system includes a simulation engine to determine a plurality of thermal states that will be experienced by powder at a voxel of a three-dimensional print volume as a result of printing a particular build. Each thermal state corresponds to a time during the printing or cooling from the printing. The system includes a stress engine to calculate a stress to the powder at the voxel based on the plurality of thermal states. The system includes a degradation engine to determine an amount of degradation of the powder at the voxel based on the stress.

Abstract: In some examples, a request to print a first three-dimensional (3D) part is received. In response to determining that the first 3D part is not similar to any 3D part referred to by an information base, a representation of the first 3D part is extracted, an indication to conduct an operation to produce a design rule for the first 3D part is sent. In response to determining that the first 3D part is similar to a matching 3D part referred to by the information base, a design rule for the matching 3D part is retrieved to print the first 3D part, where the design rule for the matching 3D part specifies a dependency of a property of the matching 3D part on an aspect associated with printing the matching 3D part.
