Claim 11:
12. A non-transitory computer readable medium on which is stored machine readable instructions that, when executed by a processor, cause the processor to:
identify, in a three-dimensional (3D) model, a color and a geometry of a boundary portion of a 3D object to be fabricated via an additive manufacturing process in which build material particles are deposited on a layer-by-layer basis and selectively fused;
determine a temperature associated with the boundary portion based on the color and the geometry of the boundary portion, the temperature corresponding to a thermal response of the build material particles and one or more colorants, a fusing agent, and/or a detailing agent applied thereon to applied energy;
select, based on the temperature determined based on the color and the geometry of the boundary portion, a first composition of the one or more colorants, the fusing agent, and/or the detailing agent to be applied onto the build material particles to fabricate the boundary portion; and
select, based on the temperature determined based on the color and the geometry of the boundary portion, a second composition of the one or more colorants, the fusing agent, and/or the detailing agent to be applied onto the build material particles in an external section that is adjacent to the boundary portion but that is not part of the 3D object; and,
cause the 3D object to be fabricated via the additive manufacturing process using the determined first agent composition for the boundary portion and the determined second agent composition for the external section,
wherein the first agent composition and the second agent composition are selected such that the boundary portion and the external section are fabricated to have the color of the boundary portion while maintaining the external section separate from the boundary portion such that the external section is not fused with the boundary portion.
