Abstract: According to one example, there is provided a three-dimensional printing system that comprises first and second build material supports adjacent to opposite sides of a build platform, when installed, a distributor to distribute build material, and a spreader for spreading build material. The three-dimensional printing system also comprises a controller to control the distributor to form a pile of build material before a first side of the build platform, to control the spreader to spread across the build platform and to form a pile of excess build material beyond a second side of the build platform, to control the spreader to move to the other side of the pile of excess build material, and to control the spreader to spread the pile of excess build material across the build platform to form a pile of excess build material on the first side of the build platform.

Abstract: In some examples, an apparatus can include a pawl including an anti-rotation surface and a spring, and a valve housing including a wedge, where the spring biases the pawl to a first position in response to the valve housing being at a closed position such that the wedge of the valve housing contacts the anti-rotation surface of the pawl to prevent rotation of the valve housing at the first position of the pawl.

Abstract: An example printing device and method of the printing device is disclosed. A print substance usage parameter is determined based on a signal provided from a sensor coupled to a refillable reservoir in the printing device. A fill level of the refillable reservoir is dynamically adjusted with the print substance usage parameter.

Abstract: Example printer finishing apparatus are described herein. An example printer disclosed herein includes an alignment guide, a track to align a sheet relative to the alignment guide, a clamp to move between a raised position and a lowered position relative to the sheet, and a force applicator coupled to the clamp. The force applicator is to cause the sheet to engage the alignment guide when the clamp is in the lowered position.

Abstract: In an example implementation, an example printer system includes a lift, an indicator, a trigger, and a reset mechanism. In an example implementation, a lift is orientable by an amount of media when adjacent to the lift and a trigger has a first portion engageable with the lift at a first orientation of the lift. In an example implementation, the trigger causes the indicator to move towards a first location relative to an aperture defined by an exterior surface in response to engagement with the lift. In an example, the reset mechanism has a first portion engageable with the lift at a second orientation of the lift and the reset mechanism causes movement of the indicator away from the first location in response to engagement with the lift.
