Patent attributes
An arrangement includes a processing chamber, a coating platform located in the processing chamber, and a coating device with a coating element located in the processing chamber for coating a metal or ceramic powder. The arrangement also has an exchanging device for exchanging at least one portion of the coating element with another portion of the same coating element or for exchanging the entire coating element with another coating element within the processing chamber when the processing chamber is closed. The exchanging device can include a multiple head, e.g., a pivoting head or revolving head, an exchanging station, and/or a moving device that allows a coating element portion that is to be exchanged to be moved or pushed away. A part of the coating element can also be rolled on a supply roller, and the coating element portion can be exchanged by unrolling the coating element from the supply roller.
