    Abstract: Disclosed herein is a print head maintenance cartridge, a printing device and a method of cleaning a print head. The print head maintenance assembly comprises a maintenance cartridge that is movable along a first direction and a wiper assembly comprising a wiper element for wiping a print head. The wiper element extends along the first direction. The maintenance cartridge comprises a guide rail extending along the first direction. The guide rail is to engage with the wiper assembly to adjust a position of the wiper element depending on a relative position between the maintenance cartridge and the wiper assembly in the first direction.

    Abstract: In one example, a pneumatic transport system to transport build material in an additive manufacturing machine includes a conduit, a source of air pressure to pull or push a stream of air through the conduit, a source of build material to introduce a build material into the stream of air, a separator to remove build material from the stream of air, a flow meter downstream from the separator to measure the stream of air flowing through the conduit, and a controller operatively connected to the flow meter and to the source of air pressure and/or the sources of build material to, based on a measurement from the flow meter, adjust a rate of flow of the stream of air in the conduit.
