Abstract: Examples of methods are described. In some examples, a method includes determining, using a variational autoencoder model, a latent space representation. In some examples, the latent space representation is of object model data. In some examples, the method includes predicting manufacturing powder degradation. In some examples, predicting the manufacturing powder degradation is based on the latent space representation.

Abstract: In an example, an apparatus includes an image processing system, a print engine, and a vision system. The image processing system generates electronic signals based on a model of an object to be fabricated using an additive manufacturing process. The print engine performs the additive manufacturing process in a plurality of passes based on the electronic signals. The vision system acquires a plurality of thermal images of the plurality of passes and assigns individual passes to individual images based on data acquired during a build of a calibration object by the additive manufacturing process. The print engine may further include a material coater to spread a powder coating material, a plurality of fluid ejection devices to eject a fusing agent, and an emitter to emit energy to fuse the fusing agent and the powder coating material into a layer of the object to be fabricated.

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: Examples disclosed herein relate to selecting a 3D printing parameter based on voxel property association and conflict resolution. In one implementation, a processor assigns properties to a voxel of a 3D print object based on a first and second zone including the voxel and a condition of a first property associated with the first zone and a condition of a second property associated with the second zone. The processor may update the assigned properties to resolve conflicts between the properties and select a 3D printing parameter based on the assigned properties.

Abstract: A method of custom print mode generation in a three-dimensional (3D) printing device may include printing a plurality of parts with a plurality of 3D printing devices, the parts each being printed using different process parameters, and capturing a plurality of images of the parts. The method may also include, with an image analysis module, analyzing the images to classify the parts into a plurality of defect gradings, and adjusting a number of the process parameters based on characteristics of the parts identified by a user as undesirable. The examiner may also include, with a recommending module, creating a custom print mode based on the parts defect gradings and adjusted process parameters.

Abstract: 3-D printing batch analysis is disclosed. A disclosed example apparatus includes a processor to generate a plurality of batches, wherein each of the batches represent an arrangement of a plurality of parts to be printed in a volume, discretize the batches into slices, and determine risk values of the slices based on the respective geometric primitives. The processor is to also determine aggregate risk values corresponding to the batches based on the risk values of the slices of the respective batches, and select a batch of the plurality of batches based on the aggregate risk values. The example apparatus also includes a printer to print the selected batch in the volume.
