Abstract: A composition for additive manufacturing is provided. The composition comprises a solvent and a rubber dissolved in the solvent, wherein the ratio of rubber to solvent is in a range of 1:10 to 3:5. A method of manufacturing an object is also provided. The method includes forming a first layer of the object by dispensing a printable composition comprising rubber dissolved in a solvent, in a ratio of 1:10 to 3:5 allowing at least a portion of the solvent in the first layer to evaporate, adding a second layer to the first layer by dispending a printable composition comprising a rubber dissolved in a solvent in a ratio of 1:10 to 3:5 and allowing at least a portion of the solvent in the second layer to evaporate.
