Abstract: Examples Include apparatuses and methods for generating three-dimensional objects. An example apparatus comprises an agent distributor and a wiping element disposed at a service location. The apparatus further comprises at least one airflow component disposed proximate the service location to generate airflow across the wiping element to reduce build material collection on the wiping element.

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: An additive manufacturing system may include a fluid ejector. The fluid ejector may be movable across a build material distributor at a maximum speed of less than or equal to 40 inches per second. The fluid ejector may include a nozzle having a non-circular bore.
