Abstract: Examples of methods for generating supports are described herein. In some examples, a method includes determining a starting position from a set of voxels of a three-dimensional (3D) object model to be additively manufactured. In some examples, the method also includes generating a support for the 3D object model by traversing a cost field from the starting position.

Abstract: An example of an apparatus is provided. The apparatus includes an input device to receive design data. The design data includes information about a geometry and load characteristics of an object. The apparatus further includes a structural design engine to generate print data to print the object on a three-dimensional printer based on the design data. The apparatus also includes a fluid design engine to generate fluidic data. The fluidic data represents a fluid channel within the object. In addition, the apparatus includes an output engine to generate an output file based on the print data and the fluidic data

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: Examples disclosed herein relate to a likelihood of success of a remote document service. For example, a processor may determine to transmit information about a remote document service to a device based on a likelihood of success associated with the ability of the device to perform the remote document service. The likelihood of success may be based on the performance history of the device and a factor associated with performance history and likelihood of success

Abstract: Examples of methods are described. In some examples, a method includes determining, using a variational autoencoder model, a latent space representation based on a three-dimensional (3D) input. In some examples, the 3D input represents a build of manufacturing powder. In some examples, the method includes predicting manufacturing powder degradation based on the latent space representation.

Abstract: Examples of structures are described herein. In some examples, a structure includes a lattice of posts. In some examples, the lattice of posts forms an opening between the posts. In some examples, the structure includes an appendage attached to a post of the posts. In some examples, the appendage extends over the opening. In some examples, the appendage is non-load bearing.

Abstract: A computing device comprising a controller is disclosed herein. The controller is to access print data of a virtual build volume including a 3D object to be generated by a 3D printer; modify the print data to include a 3D structure at a location within the build volume to encapsulate an amount of build material; receive powder degradation data corresponding to the powder degradation of the encapsulated amount of build material; and calibrate an additive manufacturing parameter based on the powder degradation data.

Abstract: Examples of methods for iterative model compensation are described herein. In some examples, a method includes predicting, in an iteration, a deformed model based on an object model. In some examples, the method includes determining, in the iteration, a disparity between the object model and the deformed model. In some examples, the method includes determining, in a next iteration, a compensated model based on the disparity and a relaxation factor.

Abstract: Examples of methods for powder reclamation are described. In some examples, a method includes estimating powder degradation for voxels of a three-dimensional (3D) manufacturing build based on a simulation. In some examples, the method includes determining a quantity of reclamation powder. In some examples, the quantity of reclamation powder may be determined based on the estimated powder degradation.
