Abstract
A method for fabricating a three-dimensional object including depositing a first amount of an ultraviolet curable phase change ink composition comprising an optional colorant and a phase change ink vehicle comprising a radiation curable monomer or prepolymer; a photoinitiator; a reactive wax; and a gellant upon a print region surface; successively depositing additional amounts of the ultraviolet curable phase change ink composition to create a three-dimensional object; and curing the ultraviolet curable phase change ink composition.
