Abstract
Additive manufacturing compositions and methods may include a resin stabilized pigment. The pigment may be easily combined with at least one component of a co-reactive system, such as a co-reactive prepolymer formulation, via solid mixing without the need for grinding or additional solvents. The prepolymer formulation may be pigmented, printed, and cured under ambient conditions, and one or more pigments may be incorporated into the composition to change the color of the composition during printing and/or to selectively change the color of the printed article among several colors.
