Abstract: Certain examples described herein relate to producing three-dimensional objects using additive manufacturing systems. These examples combine the use of material volume coverage vectors to define object data with octree data structures and models for tracking material placement error and available volumes. Material volume coverage vectors correspond to a volumes of threedimensional objects and define a probabilistic distribution of materials available to an additive manufacturing system including combinations of said materials. In certain examples, a bottom level of the error tracking octree model is constructed to contain at least a portion of the data values for a set of obtained material volume coverage vectors. This is then used in an error distribution process to generate manufacturing control data for the additive manufacturing system.

Abstract: A method is described in which data representing a three-dimensional object to be printed is obtained. The data comprises object property data indicative of properties of the three-dimensional object. Layers within the three-dimensional object to be printed are identified. The obtained data is processed by comparing object property data associated with an identified layer to object property data associated with a reference layer selected from the identified layers. Where a difference in object property data associated with an identified layer and object property data associated with a reference layer is determined, the determined difference is stored.

Abstract: In an example, a method includes receiving, at at least one processor, object model data representing at least a portion of an object that is to be generated by an additive manufacturing apparatus by fusing build material within a fabrication chamber. An indication of an intended object placement location within the fabrication chamber may be determined, and a plurality of predefined locations within a fabrication chamber may be identified based on a volumetric extent of the object or object portion if placed in its intended object placement location, wherein the predefined locations are related to dimensional compensation values. A dimensional compensation value to apply to the object model data may be determined by combining the dimensional compensation values relating to the identified plurality of predefined locations and applied to the object model data to generate modified object model data.
