Abstract: In an example implementation, a media tray assembly for use in an imaging device includes a media width adjuster having a bottom portion and a top portion. The top portion of the media width adjuster is extendable between a first stable position and a second stable position. The media tray assembly also includes a tension spring to drive the top portion to the stable positions.

Abstract: A three-dimensional printing system may include a build platform, the build platform including at least one hole defined through the build platform, a diffuser plate placed below the at least one hole to maintain an amount of build material between a lower surface of the build platform and an upper surface of the diffuser plate, and a flow channel defined around the diffuser plate and sealing the diffuser plate from atmosphere.

Abstract: In one example, a platform lift includes a rotationally stationary leadscrew to support a platform, a rotatable nut to drive the leadscrew up and down through a range of motion, a first spring to apply a continuous downward force to the leadscrew throughout the range of motion, and a second spring to apply a continuous upward force to the leadscrew throughout the range of motion.
