Abstract: A method includes processing circuitry acquiring a first indication of an extent of fusion of build material forming a first object generated by an additive manufacturing apparatus. A second indication of an extent of fusion of build material forming a second object generated by the additive manufacturing apparatus in a second additive manufacturing operation may also be acquired, wherein in the first operation, the fusing energy modules are controlled to provide energy at a first energy level and in the second operation, the fusing energy modules are controlled to provide energy at a second energy level, different from the first energy level. An energy contribution of each of the fusing energy modules to a zone of the additive manufacturing apparatus in which the first and second objects were generated may be determined and based on the indications of extent of fusion and the contributions of the fusing energy modules.
