Abstract
In an example method for generating a site-specific alloyed section of a three-dimensional (3D) object during three-dimensional printing, individual layers of a metal-based build material are patterned, based on a digital 3D object model of the 3D object, with a binder agent to form an intermediate structure. A first portion of at least one of the individual layers is patterned, based on the digital 3D object model, with an alloying agent to form a pattern of the site-specific alloyed section. A second portion of at least one of the individual layers is patterned, based on the digital 3D object model, with a diffusion barrier agent to form a perimeter pattern at an edge of at least a portion of the site-specific alloyed section. The intermediate structure is exposed to a heat treatment to form the 3D object.
