Abstract: An example technique for creating a voxel representation of a three dimensional (3-D) object can include obtaining a shape specification of a 3-D object and a number of 3-D objectives. The example technique for creating a voxel representation of the 3-D object can also include creating a voxel representation of the 3-D object by assigning a material type from a number of material types to each voxel of the voxel representation that defines the 3-D object. The example technique creating a voxel representation of a 3-D object can also include evaluating the voxel representation to determine whether the number of objectives are met.

Abstract: A system is provided for processing slice data representing a slice of a three-dimensional object to be generated by an additive manufacturing system. The system includes a processor to perform, when the additive manufacturing system is to generate the slice, a transformation on the slice data based on characteristic data of the additive manufacturing system, the slice data derived from three-dimensional object design data.

Abstract: A sensor may be to detect a property indicative of a print dead zone caused by a defect of build material to be used for generating the three-dimensional object or a malfunction of a heater that is to heat the build material, a build material distributor that is to provide the material, or a carriage. A processor may be to receive, from the sensor, dead zone data relating to the print dead zone, and to prevent the malfunction of the heater, the build material distributor, or the carriage, or to modify data representing the three-dimensional object to cause the three-dimensional object to be shifted such that three-dimensional object is to be printed outside the print dead zone.

Abstract: In some examples, octree serialization can include non-transitory machine-readable medium storing instructions, the instructions executable by a processing resource to evaluate two or more nodes sequentially in an octree structure until a leaf node is reached, wherein the two or more nodes include at least one non-leaf node, and generate a serialized octree document based on a respective node identifier in a header associated with each node of the two or more nodes.

Abstract: Measures for use in an additive manufacturing system. A thermal camera measures temperatures of a printbed area of the system at a first time and a second, subsequent time during additive manufacture of an object in the printbed area. A controller receives, from the thermal camera, temperature information associated with the measured temperatures at the first time and the second time and processes the received temperature information to determine a first position of a moving part of the system at the first time and a second position of the moving part at the second time. In response to the processing indicating that the moving part has not moved by a sufficient amount between the first time and the second time, the controller determines that the moving part is operating abnormally.

Abstract: An example technique for generating slice data from a voxel representation can include obtaining a shape specification of the 3-D object. The example technique for generating slice data from a voxel representation can also include obtaining a material specification of the 3-D object. The example technique for generating slice data from a voxel representation can also include merging the shape specification and the material specification to create a voxel representation of the 3-D object, wherein each voxel in the voxel representation includes a plurality of data types. The example technique for generating slice data from a voxel representation can also include generating slice data from the voxel representation, wherein the slice data provides a higher resolution than that provided by the voxel representation using the plurality of data types.

Abstract: A sensor may be to detect a height profile of build material for generating the three-dimensional object. A defect of the build material may be determined to exist based on the height profile of the build material. The defect may be corrected or the defect may be prevented from impacting a component of the system. A portion of a layer of the build material delivered by a build material distributor may be selectively solidified.

Abstract: A method and apparatus partition a AM build bed of a AM unit into a first virtual build bed and a second virtual build bed. The first virtual build bed is assigned to a first user while the second virtual build bed assigned to a second user. A first digital file for a first object to be generated in the first virtual build bed is received from the first user. A second digital file for a second object to be generated in the second virtual build bed is receive from the second user. Output signals are transmitted to the AM unit to generate the first object in the first virtual build bed and the second object in the second virtual build bed during a build cycle.
