Abstract: In some examples, a data representation is received that includes voxels relating to a volumetric property and a functional property of portions of a three-dimensional (3D) object to be formed by a 3D printing system, and trajectory voxels containing information to guide operation of a machine that manipulates portions of the 3D object during 3D printing. Information of the voxels relating to the volumetric property and the functional property and the information of the trajectory voxels are combined to produce instructions that control the 3D printing system to build the 3D object.

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: In one example in accordance with the present disclosure, an electronic device is described. An example electronic device includes a processor and memory storing executable instructions that when executed cause the processor to receive an image of a polymer melt pool captured during crystallization of the polymer melt pool. The instructions also cause the processor to measure brightness of the polymer melt pool in the captured image. The instructions further cause the processor to determine crystallization information of the polymer melt pool based on the measured brightness of the polymer melt pool.

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.
