Composition

A three-dimensional (3D) printing kit, comprising:

• a build material composition, including:
• a host metal present in an amount ranging from about 95.00 weight percent to about 99.99 weight percent, based on a total weight of the build material composition;
• and
• a flow additive present in an amount ranging from about 0.01 weight percent to about 5.00 weight percent, based on the total weight of the build material composition, wherein the flow additive consists of a metal containing compound that is reducible to an elemental metal in a reducing environment at a reducing temperature less than a sintering temperature of the host metal, wherein the elemental metal is capable of being incorporated into a bulk metal phase of the host metal in a final metal object, wherein the composition is spreadable, having a Hausner Ratio less than 1.25;
• and
• a binder agent to be applied to at least a portion of a layer of the build material composition via an inkjet printhead to pattern a cross-section of an intermediate structure.
