Abstract

Provided is a method for producing a three-dimensional (3D) molded article capable of being cured without consuming energy specifically intended for curing such as heating or light irradiation. The method for producing a three-dimensional (3D) molded article comprises the steps of: i) applying a first room temperature-curable organopolysiloxane composition onto a base material using a 3D printing device to form a first layer, wherein the first room temperature-curable organopolysiloxane composition exhibits a thixotropy index of 5 or higher and lower than 10; ii) allowing the first layer under non-heated conditions to form a partially cured first layer; iii) applying a second and optionally further one or more subsequent room temperature-curable organopolysiloxane compositions onto the partially cured first layer using a 3D printing device to form a second and optionally further one or more subsequent layers, wherein each composition has a thixotropy index of 5 or higher and lower than 10; and iv) allowing the second and optionally further one or more subsequent layers under non-heated conditions during each layer formation to form a partially cured second and optionally further one or more subsequent layers.
