Abstract: A shaping composition for controlling deformation of a green body object can include from about 10 wt % to about 80 wt % liquid vehicle, and from about 10 wt % to about 90 wt % metal particulates. The metal particulates can include from about 35 wt % to about 90 wt % high melting point metal particles, from about 10 wt % to about 65 wt % aluminum alloy particles, and from about 0.1 wt % to about 10 wt % metal complex selected from an inorganic metal salt, an organic metal salt, or a metal oxide. The metal of the metal complex can include copper, iron, aluminum, chromium, titanium, cobalt, silver, gold, nickel, tin, or zinc.

Abstract: An example of a method, for three-dimensional (3D) printing, includes applying a build material and patterning at least a portion of the build material. The patterning includes selectively applying a wetting amount of a binder fluid on the at least the portion of the build material and subsequently selectively applying a remaining amount of the binder fluid on the at least the portion of the build material. An area density in grams per meter square meter (gsm) of the wetting amount ranges from about 2 times less to about 30 times less than area density in gsm of the remaining amount.

Abstract: A device for forming spherical particles may include a receiving chamber having a heating portion and a cooling portion. Wire segments may travel in a free fall through the receiving chamber. While falling through the heating portion, wire segments may be heated to form spherical particles in response to exposure to microwave electromagnetic radiation. While falling through the cooling portion, formed spherical particles cool.
