Abstract

See full text

In an example three-dimensional printing method, individual layers of a metal-based build material are patterned, based on a 3D object model, with a binding agent to form an intermediate structure. A case-hardened portion of a 3D object is also patterned (based on the object model) by selectively depositing a hardening agent to deliver a predetermined concentration of a hardening element to at least one of the individual layers, wherein the individual layers are maintained below a vaporization temperature of the hardening agent during the selectively depositing. The intermediate structure is heated at a first rate to a temperature that aids in diffusion of the hardening element, and is held at the temperature for a predetermined time. The intermediate structure is cooled at a second rate. The intermediate structure, with the patterned case-hardened portion, is then sintered at a sintering temperature of the metal-based build material.
