Abstract: An object of the present invention is to provide a novel polymer composition for stereolithography that is capable of suitably providing an elastic molded product by stereolithography. A polymer composition for stereolithography containing a liquid polymer and a monomer, the polymer composition for stereolithography having a viscosity of 3,000 mPa·s or less, the viscosity being measured in an environment of a temperature of 25° C. and a relative humidity of 50% using an E-type viscometer under conditions of a cone plate diameter ? of 25 mm and a shear rate of 100 sec?1.

Abstract: There is provided a rubber composition for additive manufacturing that allows a rubber shaped article to be favorably produced using an additive manufacturing apparatus, and allows the obtained rubber shaped article to achieve both high mechanical strength and excellent elongation. The rubber composition for additive manufacturing comprises a liquid rubber, an amine-based urethane acrylate oligomer, and a monomer, wherein a total content of the amine-based urethane acrylate oligomer and the monomer is 30 parts by mass or more, per 100 parts by mass of the liquid rubber.
