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.

A media-sheet stacking system for stacking media sheets on a device output tray comprises a kicker to advance a media sheet along the output tray by pushing a trailing edge of the media sheet as it exits the device, and a movable element arranged to face the output tray across a space that receives media sheets exiting the device. A drive mechanism is provided to drive the movable element in the direction of advance of the media sheet along the output tray.
