1. A composition suitable for support in building a three dimensional object, said composition comprising:
- at least one curable component,at least one non-curable component, said non-curable component being a polyol or glycol compound,wherein none of said non-curable components is reactive with any of said curable components;
a surface additive for reducing surface tension; and
a stabilizer;
wherein all components of the composition are either miscible or soluble in the composition and said composition has a first viscosity of 100-500 cps at ambient temperature and a second viscosity of <
20 cps at a temperature higher than said ambient temperature;
wherein, after irradiation, said composition results in a solid, a semi solid or a gel material capable of dissolving or swelling upon exposure to water, to an alkaline or acidic water solution or to a water detergent solution.

Abstract
Compositions suitable for support in building a three-dimensional object are described. The compositions may include a non-curable component and a curable component not reactive with the non-curable component. The composition may further include a surface-active agent and a stabilizer, wherein the composition has a first viscosity of about 20-500 cps at ambient temperature, and a viscosity lower than 20 cps at a temperature higher than the ambient temperature. After irradiation, the composition results in a solid, a semi-solid or liquid material.
