Abstract: Examples of methods for thermal image generation are described. In some examples, a method may include determining a score map based on first features from a model, a simulated thermal image at a first resolution, and second features of the simulated thermal image. In some examples, the method may include generating a thermal image at a second resolution based on the score map, the first features, and the second features, where the second resolution may be greater than the first resolution.

Abstract: An example system includes a simulation engine to determine a plurality of thermal states that will be experienced by powder at a voxel of a three-dimensional print volume as a result of printing a particular build. Each thermal state corresponds to a time during the printing or cooling from the printing. The system includes a stress engine to calculate a stress to the powder at the voxel based on the plurality of thermal states. The system includes a degradation engine to determine an amount of degradation of the powder at the voxel based on the stress.

Abstract: In some examples, a request to print a first three-dimensional (3D) part is received. In response to determining that the first 3D part is not similar to any 3D part referred to by an information base, a representation of the first 3D part is extracted, an indication to conduct an operation to produce a design rule for the first 3D part is sent. In response to determining that the first 3D part is similar to a matching 3D part referred to by the information base, a design rule for the matching 3D part is retrieved to print the first 3D part, where the design rule for the matching 3D part specifies a dependency of a property of the matching 3D part on an aspect associated with printing the matching 3D part.

Abstract: In some examples, a distribution of values of a property of a given layer to be printed as part of three-dimensional (3D) printing is predicted, wherein the predicting is based on a distribution of values of the property in a previous layer that has been printed as part of the 3D printing. 3D printing of an object is controlled based on the predicted distribution of values of the property of the given layer.

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: 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 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.
