Abstract: In one example, a refill control system to control the flow of powdered build material to a dispenser to periodically refill the dispenser with powdered build material. In one example, the refill control system includes a container to hold powered build material and a valve operable between a closed position to block a flow of powdered build material from the container to the dispenser and an open position to not block the flow of powdered build material from the container to the dispenser. The container is movable from a first position to a second position to connect the container to the dispenser and from the second position to the first position to disconnect the container from the dispenser.
