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: In one example in accordance with the present disclosure, a method is described. According to the method, profile information is acquired for a layer of a volume of build material in an additive manufacturing system. From the profile information, a per thermal voxel attribute of build material particles is approximated. An operation of the additive manufacturing system is adjusted based on an approximated per thermal voxel attribute.

Abstract: According to examples, a three-dimensional (3D) fabrication system may include fabrication components and a controller. The controller may control the fabrication components to fabricate parts of a 3D object in a build envelope, the parts to be assembled together to form the object, and in which the parts are fabricated at locations corresponding to relative positions of the parts with respect to each other in the assembled object. The controller may also control the fabrication components to fabricate a cage around the parts in the build envelope.

The plurality of kernels are generated based on applying a neural network to the description of the physical state. The system includes a calculation engine to apply the plurality of kernels to the description of the physical state to produce a plurality of intermediate descriptions. The system includes a weighting engine to determine a plurality of weight maps based on the plurality of kernels. The system includes a compositing engine to apply the plurality of weight maps to the plurality of intermediate descriptions to produce weighted intermediate descriptions and to combine the weighted intermediate descriptions to produce an updated description of the physical state.

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: Examples disclosed herein relate to simulating production of an order. In one implementation, a processor extracts information about process flow of an order through resources, resource policy, and prioritization within the production environment from information related to the fulfillment of the previous orders. The processor may create a simulation of the fulfillment of new orders within the production environment based on the extracted information.

Abstract: An example three-dimensional (3D) printer may include a camera to capture a low-resolution thermal image of a build material bed. The 3D printer may include an interpolation engine to generate an interpolated thermal image based on the low-resolution thermal image. The 3D printer may also include a correction engine to enhance fine details of the interpolated thermal image without distorting thermal values from portions of the interpolated thermal image without fine details to produce an enhanced thermal image.

Abstract: A parts packing method is used to optimize build bed part placement for additive manufacturing. The method includes a user interface to parts packing software, enabling a process engineer to select parts from a pool of parts, group parts to have uniform orientation, and specify a range of angles and rotation of the parts. Additionally, the user interface accepts input related to process variations among different printers as well as drift over time of a single printer. The user interface feeds the data into the parts packing program to optimize build bed part placement.
