Abstract: Examples of methods for determining an adaptive thermal diffusivity kernel are described herein. In some examples, an adaptive thermal diffusivity kernel is determined based on a map. In some examples, a temperature is predicted based on the adaptive thermal diffusivity kernel. In some examples, the map includes a temperature map, a shape map, or a concatenation of the temperature map and the shape map.

Abstract: Examples disclosed herein relate to determining a manufacturing batch. In one implementation, the manufacturing batch relates to 3D printing. A processor may determine component parts of a product that. In one implementation, a processor determines a batch of the component parts related to different products based on a comparison to other potential batches.

Abstract: Examples disclosed herein relate to 3D printer fresh and recycled powder supply management. In one implementation, a processor estimates fresh and recycled powder use and recycled powder creation by a 3D printer based on a set of print jobs. The processor may coordinate fresh and recycled powder resources based on the powder estimate and stored information about powder resources

Abstract: One example includes a non-transitory machine readable storage medium including voxels organized by an octree and at least one quad-tree index. The octree defines an object to be three-dimensionally printed and includes a list of nodes for each depth of the octree where each node includes nodal content representing at least one voxel. The at least one quad-tree index is to index at least one node of the octree and has a depth less than or equal to a maximum resolved depth. The at least one quad-tree index is to be accessed by computer executable instructions to retrieve nodal content from the octree to control a processor to process the object to be three-dimensionally printed.

Abstract: According to an example, a processing device may slice a 3D model along a first direction to generate a plurality of layers in parallel planes defined across a second direction and a third direction, in which each of the plurality of layers is composed of respective polygons representing portions of the 3D model. The plurality of layers may be partitioned into a plurality of stacked boxes containing the respective polygons and for each stacked box of the plurality of stacked boxes, the polygons in the stacked box may be assembled into a superset polygon and the superset polygon may be partitioned into bounding shapes. A shape profile of the 3D object may be generated using the bounding shapes.

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: The present disclosure is drawn to particulate mixtures, material sets and methods of forming porous 3-dimensional printed parts. The particulate mixtures can include 5 wt % to 40 wt % of a salt having an average particle size from 5 μm to 100 μm. The mixture can also include 60 wt % to 95 wt % of a build material for 3-dimensional printing. The build material can include a particulate polymer having an average particle size from 5 μm to 100 μm and a melting point from 100° C. to 400° C. The melting point of the particulate polymer can be lower than the melting point of the salt.

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: Scheduling of manufacturing jobs is described herein. In accordance with an example, the scheduling of manufacturing jobs includes obtaining an order parameter associated with a product to be manufactured on a manufacturing equipment set. A product dimension of an intermediate product for the product is determined based on the order parameter and a production attribute. Further, the manufacturing job is scheduled for the product amongst manufacturing jobs for other products to be manufactured on the manufacturing equipment set, based on the product dimension of the intermediate product and a scheduling criterion. The scheduling criterion can be a parameter to regulate the scheduling of the manufacturing jobs on the manufacturing equipment set.
