Abstract: Described herein are methods and systems for printing a three-dimensional object. In an example, a method for printing a three-dimensional object can comprise: (i) a metallic build material being applied; (ii) a binder fluid being applied on at least a portion of the metallic build material; (iii) the selectively applied binder fluid can be flash fused to bind the metallic build material and the selectively applied binder fluid by application of an energy flux having an energy density of from about 0.5 J/cm2 to about 20 J/cm2 for less than about 1 second. In the example, (i), (ii), and (iii) can be repeated at least one time to form the three-dimensional object. The binder fluid can comprise a liquid vehicle and polymer particles dispersed in the liquid vehicle

Abstract: In a three-dimensional (3D) printing method example, a metallic build material is applied. A binder fluid is selectively applied on at least a portion of the metallic build material. The binder fluid includes a liquid vehicle and polymer particles dispersed in the liquid vehicle. The application of the metallic build material and the selective application of the binder fluid are repeated to create a patterned green part. The patterned green part is heated to at about a melting point of the polymer particles to activate the binder fluid and create a cured green part. The cured green part is heated to a thermal decomposition temperature of the polymer particles to create an at least substantially polymer-free gray part. The at least substantially polymer-free gray part is heated to a sintering temperature to form a metallic part.
