1. A method comprising:
acquiring, by a processor, data characterizing geometrical modifications to apply to compensate for anticipated deformations in additive object manufacture, the geometrical modifications associated with a plurality of additive manufacturing apparatuses;
acquiring, by the processor, a data set indicating deviations between intended object dimensions of calibration objects and actual object dimensions of the calibration objects as generated by a specific additive manufacturing apparatus;
modifying, by the processor, the data characterizing the geometrical modifications associated with the plurality of additive manufacturing apparatuses based on the data set for the specific additive manufacturing apparatus;
deriving, by the processor, an apparatus-specific geometrical compensation model based on the modified data, the apparatus-specific geometrical compensation model compensating for the anticipated deformations in additive object manufacture by the specific additive manufacturing apparatus;
modifying, by the processor, object model data for an object by applying the apparatus-specific geometrical compensation model to the object model data; and
causing, by the processor, the specific additive manufacturing apparatus to additively manufacture the object in accordance with the modified object model data.
