1. A three dimensionally printable curable composition comprising:
a polybutadiene urethane (meth)acrylate in an amount of about 25 to about 35 percent by weight;
a maleated isoprene (meth)acrylate in an amount of about 25 to about 35 percent by weight;
a (meth)acrylate monomer wherein the (meth)acrylate monomer is present in an amount greater than either of the polybutadiene urethane (meth)acrylate or the maleated isoprene (meth)acrylate; and
a photoinitiator, wherein the percent by weight is based on the total composition, and wherein when three dimensionally printed cured products of the composition exhibit at least one of the following physical properties: percent elongation of greater than about 115, modulus of greater than about 3, tensile strength of greater than about 2 and tear strength of greater than about 10 kN/m and after exposure to an elevated temperature condition and/or radiation in the electromagnetic spectrum at a second wavelength, the composition exhibits at least one of the following physical properties: percent elongation of greater than about 115, modulus of greater than about 30, tensile strength of greater than about 9 Mpa·s and tear strength of greater than about 28 KN/m.
