On the future printing platform there is planned to be a water vaporizer that adds water to the
blowing station air for cooling and reduction of pen crusting. The water is supplied via a large
storage tank that must be regularly filled. Additionally, it is planned to have a rebreather which takes
the exhaust air from the printer and removes the heat energy and condenses the water vapor. This
is released to a waste collection tank or industrial drain.
