1. A radiation curing composition suitable for building a three dimensional object by a solid freeform method, the composition comprising:

  • one or more mono-functional monomers where a respective polymer has a Glass Transition Temperature higher than about 60°

    C.;

    one or more di-functional oligomers where a respective polymer has a Glass Transition Temperature lower than about 40°

    C.; and

    a filler that comprises particles having an average diameter of less than 100 nm,wherein functional groups are meth(acrylic), the composition has a viscosity of about 50-500 cps at ambient temperature, the concentration of said one or more mono-functional monomers is at least 30% by weight relative to the total weight of the composition and the concentration of said one or more di-functional oligomers is at least 20% by weight relative to the total weight of the composition.
