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.

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: Systems and methods associated with resource provisioning are disclosed. One example method includes dividing a set of printing resources into a first partition and a second partition. The example method also includes provisioning the first partition to handle print jobs from a print queue that have a specified attribute. The first partition may be provisioned when print jobs having the specified attribute exceed a first predefined threshold.

Abstract: Examples relate to providing spatial analysis using attribute graphs. In one examples, there are a number of spatial points that each represent characteristics in a dimensional space. Non-data points are generated in the dimensional space, and a Delaunay triangulation is performed using the spatial points and the non-data points to generate a plurality of edges, where interior points of the plurality of non-data points that are in an interior space of the plurality of spatial points are excluded from the Delaunay triangulation. Next, spatial edges from the plurality of edges that each connect a spatial point that is connected to a first mixed edge to another spatial point that is connected to a second mixed edge are identified, where the spatial edges are used to generate a robust contour of a cluster of the spatial points.

Abstract: Examples of methods for model prediction are described herein. In some examples, a method includes predicting a compensated model. In some examples, the compensated model is predicted based on a three-dimensional (3D) object model. In some examples, a method includes predicting a deformed model. In some examples, the deformed mode is predicted based on the compensated model.

Abstract: Examples of the present disclosure relate to a method for processing three dimensional (3D) models. The method comprises categorizing the 3D models into geometrical characteristic categories, creating a geometrical template corresponding to each category, determining a label placement for each geometrical template, assigning a label to each 3D model based on the determined label placement and assigning a packing position to the 3D models based on their corresponding template. The method is such that some categories comprise more than one 3D model.
