The invention relates to a material for the formation of protective layers resistant to high temperatures on chromium oxide forming substrates, to a manufacturing method and to a use of these materials. A user IF task accepts a reservation input for the use of a copying function using a scanner and the printer from a user while the printer job is being executed by the printer controller. The interior shelf defines a flow opening and a movable valve ball is positioned on the interior shelf and is able to move in the direction of the flow opening due to incoming fluid pressure. The pulse duration of the laser is decreased and the converted laser directing to a desired target location of soft tissue within the oral cavity. The present invention uses an aluminum source containing less contaminant compared to the prior art, thus obtaining aluminum oxide of high quality. The user device receives the information and displays it to the user.
