1. A method comprising:
obtaining, by a processor, calibration data relating to performance of a lattice structure comprising a plurality of elongate members as a function of a printed thickness of each elongate member and a position of each elongate member within a fabrication chamber of an additive manufacturing apparatus within which the lattice structure is printed;
obtaining, by the processor, an object model representing an object to be printed, the object having elongate members;
determining, by the processor, a position of the object at which the object is to be printed within the fabrication chamber;
determining, by the processor and based on the determined position of the object at which the object is to be printed within the fabrication chamber, respective positions at which the elongate members of the object are to be printed within the fabrication chamber;
modifying, by the processor, the object model such that the elongate members of the object have respective thicknesses according to the calibration data for the respective positions at which the elongate members of the object are to be printed within the fabrication chamber to yield a specified performance of the object; and
causing the object to be printed at the determined position in the fabrication chamber of the additive manufacturing apparatus in accordance with the modified object model, such that the elongate members have the respective thicknesses when printed.
