Setting properties of three-dimensional objects

Apparatus comprising:

• an obtaining module to obtain data representing a three-dimensional object to be printed, the data comprising sub-volumes representing the three-dimensional object;
• an identifying module to identify a characteristic for the three-dimensional object to be printed and a positional component of a sub-volume within the three-dimensional object;
• and
• a processor to set, based on the identified characteristic and positional component, property data for the sub-volume to be used in printing the three-dimensional object, wherein the identified characteristic and the identified positional component are a function of the property data.

A non-transitory machine-readable storage medium encoded with instructions executable by a processor, the machine-readable storage medium comprising:

• instructions to obtain data representing a three-dimensional object to be printed, the data comprising sub-volumes making up the three-dimensional object;
• instructions to obtain a characteristic for the three-dimensional object to be printed and a positional component of a sub-volume within the three-dimensional object;
• and
• instructions to set, based on the obtained characteristic and positional component, property data for the sub-volume to be used in printing the three-dimensional object, wherein the obtained characteristic and the obtained positional component are a function of the property data.
