Abstract: The present invention relates in part to a photocurable resin composition comprising a first compound formed from the reaction of a diisocyanate and an isocyanate reactive compound comprising a double bond, a second compound comprising one or more double bonds susceptible to polymerization, and a photoinitiator. The invention also relates in part to a method of making the photocurable resin composition. The invention also relates in part to a method of fabricating an article comprising the steps of providing a photocurable resin composition comprising a first compound formed from the reaction of a diisocyanate and an isocyanate reactive compound comprising a double bond, a second compound comprising one or more double bonds susceptible to polymerization, and a photoinitiator; 3D printing the photocurable resin to form an article; and curing the article. The invention also relates in part to a 3D printed resin article.
