Abstract
A method for calibrating an apparatus for producing an object by additive manufacturing, the apparatus including a process chamber for receiving a bath of material to be solidified by exposure to electromagnetic radiation, a support for positioning the object in relation to the surface level of the bath of material, and a solidifying device for solidifying a selective layer-part of the material on the surface level by electromagnetic radiation, the method including controlling the solidifying device to make a first test mark at a first delay setting, controlling the solidifying device to make a second test mark at a second delay setting different from the first delay setting, and determining a delay setting based on at least the first test mark and the second test mark.
