Three-dimensional additional object generation

An additive manufacturing system comprising:

• a processor;
• and
• a memory storing instructions executable by the processor to perform processing comprising:
• obtaining object model data relating to a three-dimensional model of an intended three-dimensional object to be generated in a build bed through selective application of print agent by a three-dimensional printer,
• obtaining deformation data to indicate that the intended object will likely be deformed during a curing process of the build bed, the curing process to include application of airflow to the intended three-dimensional object to remove print agent solvent vapor, and the deformation data including a direction of the airflow;
• and
• automatically generating modified object model data that includes a modified three-dimensional model based on the deformation data, wherein the modified three-dimensional model includes an additional object to be printed adjacent to the intended object,
• wherein the additional object is to reduce a likelihood of the intended object being deformed during the curing process, and is to designed or positioned at least in part on the basis of the direction of the airflow.

A non-transitory computer-readable medium storing instructions executable by a processor to perform processing comprising:

• receiving object model data relating to an intended object to be printed by a three-dimensional printer in a build bed;
• obtaining information relating to a direction of airflow to be applied through the build bed during a curing process;
• identifying portions of the intended object that will likely be deformed during a curing process whilst the three-dimensional object is positioned in the build bed;
• and
• generating updated object model data including a sacrificial object part to be printed at a position relative to the identified portions of the intended object based on the obtained information relating to the direction of the airflow and the identified portions,
• wherein the sacrificial object part to provide mechanical support to the intended object during the curing process.
