Abstract: Ti ink compositions for printing, such as ink jet printing, are disclosed. The ink compositions comprise a liquid dispersion of Ti hydride powder having a mean particle size of less than 10.0 microns; a liquid carrier; and at least one surfactant. Methods of making and using the disclosed inks are also disclosed. For example, a finished Ti product can be produced by printing the disclosed ink composition, such as by ink jet printing, to form a green article, heating the green article to dehydrogenate it and form a Ti containing part. The method may further comprise sintering the Ti containing part to produce a sintered Ti product. In an embodiment, the method comprises printing one or more support materials for the ink composition, that comprises solid particles of a metal oxide, a metal carbide, a metal nitride, a polymer, or combinations thereof.
