Abstract: According to an example, an apparatus for a three-dimensional printing system comprises a chamber, an actuator, and a controller. The chamber comprises an opening towards the top of the chamber to receive a container having an openable base and the container is to contain a build cake, wherein the chamber further comprises a platform movable below the opening that is to receive the build cake when the base of the container is opened. The actuator is to move the platform within the chamber, and the controller is to position the platform at a build cake receiving position such that when the container base is opened, the build cake drops onto the platform generating a shock wave that is transmitted into the build cake.

Abstract: In an example implementation according to aspects of the present disclosure, a method may include receiving a temperature reading from a sensor coupled to the head mounted unit. A delta may be calculated based on the temperature reading and a predetermined temperature. A thermo-electric cooling device may be activated based on the delta surpassing a threshold. The thermo-electric cooling device utilizes thermally conductive plates, padding and fabric to transfer thermal energy.

Abstract: An example retaining device includes a retaining feature to retain an article, and a first arm. The first arm projects in a first direction and includes a first protrusion extending away from a first face of the first arm. The first protrusion is to engage another article to retain the retaining device relative to the other article. The first arm includes a second protrusion spaced apart from the first protrusion and extending away from the first face of the first arm. The width of the second protrusion increases in the first direction so as to provide a sloped surface.

Abstract: An example method comprises operating a drive unit to advance a substrate in a substrate advance direction toward a printing station. At the printing station, a first line is printed onto the substrate. A drive unit is instructed to advance the substrate in the substrate advance direction by a target amount, and a second line is printed onto the substrate. The distance between the first and second lines in a direction perpendicular to the substrate advance direction is calculated and, based on the calculated difference, a tension of the substrate is modified.

Abstract: An image forming apparatus may include a receiving unit to receive a print request to print a document. Further, the image forming apparatus may include an extraction unit to extract content from the document. Furthermore, the image forming apparatus may include a categorization unit to determine a type of the content by applying a machine learning model to the extracted content. Further, the image forming apparatus may include a controller to manage the print request based on the type of the content.

Abstract: According to examples, an apparatus may include a body and a control panel assembly coupled to the body. The control panel assembly may include a base plate coupled to the body, a display panel coupled to the base plate, and an input device coupled to the display panel. In some examples, the control panel assembly may move from a first position in which the display panel is at least partially retracted in the body to a second position in which the display panel and the input device are extended out from the body. The display panel may be positioned at a first predefined angle relative to the base plate and the input device may be positioned at a second predefined angle relative to the display panel.

Abstract: An example non-transitory computer-readable medium includes instructions that, when executed by a processor, cause the processor to retrieve a plurality of parts to be three-dimensionally (3D) printed and an output rate indicative of a rate at which previous 3D printed parts have been output, select a packing parameter that results in a packing time corresponding to the output rate, and compute a part packing of the plurality of parts for a print bed according to the packing parameter.

Abstract: A printing apparatus has a transfer member to receive an image and transfer the image to a substrate, and an airflow management unit disposed adjacent to the transfer member to define a channel between the transfer member and the airflow management unit. The airflow management unit has an injection mechanism to inject airflow into the channel, a suction mechanism to remove the airflow from the channel, and a vortex generator to generate a vortex within the channel.

Abstract: A method of recovering polyolefin polymer from a three-dimensional printed object can include dissolving a polyolefin polymer of a three-dimensional printed object in a polyolefin-dissolving solvent to generate dissolved polyolefin polymer from the three-dimensional object, wherein the three-dimensional printed object includes from about 0.1 wt % to about 10 wt% particulate fusing compound and from about 90 wt% to about 99.9 wt% polyolefin polymer. The method can further include separating the particulate fusing compound from the polyolefin-dissolving solvent and the dissolved polyolefin polymer, and evaporating the polyolefin-dissolving solvent from the dissolved polyolefin polymer.

Abstract: In various examples, a fluid ejection device may include a fluid ejection die formed with a first material and that includes a bondpad and a plurality of fluid ejectors, and a cover layer adjacent the fluid ejection die. The cover may be formed with a second material that is different than the first material and may include a first region that overlays the bondpad and a second region that overlays the plurality of fluid ejectors. In various examples, the first and second regions are separated by a break in the cover layer. The break may be filled with a third material that is different than one or both of the first and second material.
