Abstract: In an example, a computing device includes a processor which in a reimaging operation of the computing device, may determine if a backup image to be used in the reimaging operation is available from a memory device connected to a local area network of the computing device. When the backup image is available from the memory device, the processor may acquire the backup image over the local area network. When the backup image is not available from the memory device, the processor may determine if a backup image is available from a wide area network of the computing device.

Abstract: A powder bed material can include from 80 wt % to 100 wt % metal particles having a D50 particle size distribution value from 4 μm to 150 μm. From 10 wt % to 100 wt % of the metal particles can be surface-activated metal particles having in intact inner volume and an outer volume with structural defects. The structural defects can exhibit an average surface grain density of 50,000 to 5,000,000 per mm2.

Abstract: A method of processing merged 3D geometric information in a 3D printing system is described that receives a 3D object model file representing at least two physical 3D parts to be printed, wherein the 3D object model file comprises 3D geometric information for the at least two physical 3D parts, wherein the 3D geometric information is encoded as at least one logical 3D part, wherein at least one of the at least one logical 3D part comprises merged 3D geometric information for at least a subset of the at least two physical 3D parts. From the 3D object model file, a separate set of 3D geometric information for each of the at least two physical 3D parts is extracted and each separate set of 3D geometric information is processed individually before printing the physical 3D parts.

Abstract: Examples of methods for training using rendered images are described herein. In some examples, a method may include, for a set of iterations, randomly positioning a three-dimensional (3D) object model in a virtual space with random textures. In some examples, the method may include, for the set of iterations, rendering a two-dimensional (2D) image of the 3D object model in the virtual space and a corresponding annotation image. In some examples, the method may include training a machine learning model using the rendered 2D images and corresponding annotation images.

Abstract: In some examples, an apparatus can include a syringe body including an electrical interface at a side surface of the syringe body, an interface at an end of the syringe body including an output at a distal surface of the syringe body, a print material particles reservoir located in the syringe body, and a structure to adapt a volume of the print material particles reservoir to move print material particles out of the print material particles reservoir through the output, where in response to the volume adapting structure moving from a first position to a second position, a signal is transmitted by the electrical interface.

Abstract: Fluid is continuously recirculated through a thermal fluid-ejection printhead. Prior to firing a thermal resistor of the printhead to thermally eject a drop of the fluid through a nozzle of the printhead, the fluid is recirculated on-demand through a chamber of the printhead between the nozzle and the thermal resistor. The thermal resistor is fired to thermally eject the drop of the fluid through the nozzle. The fluid has a concentration of solids greater than 12% by volume.

Abstract: In an example, a computing device is described. The computing device comprises a processor. The processor is to generate a key using a value as an input to generate the key. The processor is further to, in response to generating the key, exclude the value from future use as the input. The processor is further to store an indication of a subsequent value to use as the input to generate a subsequent key. The indication is cryptographically associated with an entity to control third-party access to the indication.

Abstract: An example system may include a processor and a non-transitory machine-readable storage medium storing instructions executable by the processor to determine a type of data to be added to a log file; determine a selected anonymization protocol for the type of the data; and anonymize the data according to the anonymization protocol as the data is added to the log file.

Abstract: Techniques for providing feedback to an actuating object are described. In an example, a device may provide a user interface having a virtual menu button that can be actuated based on a position of an object. If the virtual menu button is determined to be actuated, the device provides a haptic feedback to the object.
