Abstract

In an example implementation, a method of printing a three-dimensional (3D) object includes, applying a layer of build powder onto a printing platform and depositing a deliberate micropattern of liquid agent onto the powder within a macropattern that defines a cross-section of a 3D object to be printed. The method includes forming a microstructure from the deliberate micropattern by applying fusing energy to the powder, the microstructure comprising fused areas and sintered areas between the fused areas.
