BUILD MATERIAL COMPOSITION

An example of a method for making a build material composition for three-dimensional (3D) printing includes freezing a dispersion of flow additive nanoparticles in a liquid to form a frozen liquid containing the flow additive nanoparticles. The frozen liquid containing the flow additive nanoparticle...

Zusammenfassung:	An example of a method for making a build material composition for three-dimensional (3D) printing includes freezing a dispersion of flow additive nanoparticles in a liquid to form a frozen liquid containing the flow additive nanoparticles. The frozen liquid containing the flow additive nanoparticles is lyophilized to form flow additive agglomerates having a porous, fractal structure. The flow additive agglomerates are mixed with a host metal. The flow additive nanoparticles have an average flow additive particle size ranging from about 1 to about 3 orders of magnitude smaller than an average host metal particle size of the host metal.
