Abstract: A resin composition useful for additive manufacturing is provided, which resin composition may exhibit improved shelf life through inhibition of crystallization. Such resin composition may include a crystallization inhibitor as taught herein, and/or a prepolymer produced by reaction of an isocyanate with multiple isomers and comprising a lower percentage of the structurally symmetric isomer. Methods of forming a three-dimensional object using such resin composition are also provided.
