Zusammenfassung:	The present disclosure relates to a photocurable polysiloxane composition for 3D printing and a dental model including the same. In regard to the photocurable composition for 3D printing, including a novel polysiloxane compound according to one aspect, the cured product thereof exhibits excellent properties in terms of hardness, strength, elongation, coloring resistance against heat, coloring resistance against light, flexural properties, and biocompatibility, and thus the cured product is appropriate for use as a dental material. In addition, since the photocurable composition is liquid and thus the molecular weight and viscosity thereof is easily controllable, the photocurable composition is suitable for a 3D printing process.
