Abstract: An example of a kit for three-dimensional (3D) printing includes a host metal and fumed flow additive aggregates to be mixed with the host metal. The fumed flow additive aggregates include flow additive nanoparticles and partially fused necks between at least some of the flow additive nanoparticles. Each of the flow additive nanoparticles consists of a metal containing compound that is reducible to an elemental metal in a reducing environment at a reducing temperature less than or equal to a sintering temperature of the host metal.
