Abstract: In one example, an additive manufacturing system. An unsealed air supply enclosure for clean air is maintained at a first pressure above an ambient air pressure to inhibit unfiltered ambient air from leaking into the enclosure. An unsealed processing chamber is maintained at a second pressure below the ambient air pressure to inhibit processing chamber air from leaking out of the processing chamber. An air pathway is disposed between the air supply enclosure and the processing chamber to provide clean air from the air supply enclosure to the processing chamber.

Abstract: Certain examples described herein relate to printer (110, 210) cooling systems of three-dimensional (3D) printers. In an example of a printer (110, 210) cooling system of a three-dimensional (3D) printer (110, 210), a shared air flow volume (120, 220) is for cooling a plurality of internal printer components (130, 140, 230, 240), and a single air inlet (150, 245) delivers ambient air (160) from outside the three-dimensional (3D) printer (110, 210) to the shared air flow volume (120, 220) In certain cases, the shared air flow volume (120, 220) comprises a first air flow conduit (135, 270) for cooling a first internal printer component (130, 230) and a second air flow conduit (145, 275) for cooling a second internal printer component (140, 240). In certain examples, the first and the second air flow conduits (135, 270) are arranged at least partially in parallel.

Abstract: Example implementations relate to manual and automated task execution in a process. For example, a computing device may include a processor. The processor may initiate a process having a manual task and an automated task, the process being associated with process definitions stored in a database. The processor may send, from the database, a manual process definition associated with the manual task to a new entry in the database and an automated process definition associated with the automated task to an automated process queue. The processor may execute the automated task based on the automated process definition in the automated process queue and may execute the manual task using the manual process definition in the new entry of the database. The execution of the manual task may generate a user interface to receive data associated with the manual task.
