Title: ARRANGEMENT FOR COATING A POWDER
Abstract:
The invention relates to an arrangement (10) with a processing chamber (20), a coating platform (30) which can be found in the processing chamber (20), and a coating device with a coating element (40) which can be found in the processing chamber (20) for coating a powder, in particular a metal or ceramic powder. According to the invention, the arrangement (10) has an exchanging device (100) which is suited for exchanging at least one portion of the coating element (40) with another portion of the same coating element (40) or for exchanging the entire coating element (40) with another coating element (41, 42, 43) within the processing chamber (20) when the processing chamber (20) is closed. The exchanging device (100) can comprise a multiple head (50), in particular a pivoting head or a revolving head, an exchanging station (80), and/or a moving device (70) which allows a coating element (40) portion that is to be exchanged to be moved or pushed away. A part of the coating element (40) can also be rolled on a supply roller (230), and the coating element portion can be exchanged by unrolling the coating element from the supply roller (230). Together with the exchanging device (100), a wear determining device (300) is also preferably provided, said wear determining device being capable of measuring the wear of the coating element (40) and triggering an automatic coating element exchange or coating element portion exchange by means of the exchanging device (100).
