Abstract: A method for printing a three-dimensional part (20) with an additive manufacturing system (10), the method including printing layers of the three-dimensional part (20) and of a support structure (22) for the three-dimensional part (20) from multiple print heads (18) or deposition lines, and switching the print heads (18) or deposition line between stand-by modes and operating modes in-between the printing of the layers of the three-dimensional part (20) and the support structure (22). The method also includes performing a purge operation for each print head (18) or deposition line switched to the operating mode, where the purge operation includes printing a layer of at least one purge tower (24) from the print head (18) or deposition line switched to the operating mode.
