Claim 7:
8. A method comprising:
identifying, by a processor, a color and a geometry of a boundary portion of a three-dimensional (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;
determining, by the processor, a temperature associated with the boundary portion and corresponding to a thermal response of the build material particles and one or more colorants, a fusin a gent, and/or a detailing went applied thereon to applied energy based on the color and the geometry of the boundary portion;
selecting, by the processor and 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 the detailing agent to be applied onto the build material particles to fabricate the boundary portion;
selecting, by the processor and 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 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
causing, by the processor, 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.
