Additive manufacturing apparatus (1) for the additive manufacturing, in layers, of three-dimensional objects, and method for operating such a manufacturing apparatus. The manufacturing apparatus (1) has a production base and at least one production head (3), which is designed to discharge production material (21) in a selective manner at the production site in raster positions (44) in accordance with predetermined production rasters (49) for the respective layer. In order to create a manufacturing apparatus which ensures quick and precise layering of three-dimensional workpieces, with the possibility of processing a number of production materials, a fixing unit (24) of the production head (3) is designed to fix in a selective manner, at the respective raster positions (44), the production material (21) located at said positions. |
