  • Publication number: 20220297182
    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.
