Abstract
In an example, a method includes acquiring, by a processor and for a set of locations in a fabrication chamber for additive manufacturing, data identifying a first subset of locations associated with a first level of variability in deformations in object generation and a second subset of locations associated with a second, greater, level of variability in deformations object generation. A geometrical compensation model may be derived to compensate for anticipated deformations in object generation by a first additive manufacturing apparatus. The geometrical compensation model may comprise geometrical transformations to apply to object model data representing at least a portion of an object, wherein each geometrical transformation is associated with a location of the set of locations. The first subset of locations may be associated with geometrical transformations determined based objects generated by a plurality of additive manufacturing apparatus and the second subset of locations may be associated with geometrical transformations determined based on objects generated by the first additive manufacturing apparatus.
