Abstract: A system and method for providing three dimensional printing production quality prediction is described herein. The system may include logic to scan a region of interest associated with a layer of a plurality of parts during printing to obtain an input for the region of interest and compute an input metric associated with the layer based on the input. In response to an initial set of print jobs, at least a portion of the plurality of parts is mechanically tested to determine at least one output. In response to a production print job, a likelihood of a part of the plurality of parts to satisfy a quality specification is predicted by inputting the input metric to at least one machine learning function comprising the at least one output, wherein the at least one machine learning function is trained during the initial set of print jobs.

Abstract: In one implementation, a resource system includes an authorization engine, an interface engine and an analysis engine. In that example, the authorization engine authorizes an analysis request, the interface engine assigns a data property to the analysis request, and the analysis engine selects a synthesis routine based on the analysis request, identifies data stored in a resource group based on the synthesis routine, and causes the synthesis routine to perform using raw data in the resource group based on the data property in response to a determination that the analysis request is authorized to access the resource group.

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: An image processing system acquires a first three-dimensional model of an object. The image processing system includes a processor and storage medium encoded with instructions executable by the processor. The instructions include instructions to define a material potential function for a material. The material potential function is a function of a three-dimensional origin point of the material in the object, a three-dimensional propagation limit of the material in the object, and a three-dimensional propagation function of the material in the object. The instructions include instructions to generate a second three-dimensional model of the object based in part on the material potential function and the first model. The second model illustrates propagation of the material through an interior volume of the object at a unit level. A controller generates control signals based on the second model, and a fluid ejection engine performs an additive manufacturing process based on the control signals.

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.

Abstract: Methods and apparatus relating to three-dimensional object models are described. In one example, (i) data representing a geometrical description of a three-dimensional object defining object geometry in a geometric space and (ii) at least one object property description describing an object property in an object property space are received. The object property space and the geometric space are intersected to define an object model, wherein an object property is defined at an intersection between a described object property and defined object geometry.

Abstract: An example technique for generating slice data from the tree data structure representation of a three dimensional (3-D) object can include obtaining a shape specification of the 3-D object and obtaining a material specification of the 3-D object. The example technique for generating slice data from the tree data structure representation of a 3-D object can also include merging the shape specification and the material specification to create a tree data structure representation of the 3-D object. The example technique for generating slice data from the tree data structure representation of a 3-D object can also include generating slice data from the tree data structure.

Abstract: Examples disclosed herein relate to determining data usage effectiveness. A processor may determine data usage effectiveness information related to an entity's workflow based on workflow data collected related to the entity's operations and metrics determined based on the data. The determination may be based on a comparison of the information related to the entity's workflow to target workflow information and priority information associated with the target workflow information. The processor may output information related to the determined data usage effectiveness.

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.
