Abstract
A radiation curing composition suitable for building a three-dimensional object by a solid freeform method is disclosed. The composition includes 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. The functional groups of the components may include meth(acrylic) and the composition has a viscosity of about 50-500 cps at ambient temperature. Further, the concentration of the mono-functional monomer may be at least 30% by weight elative to the total weight of the composition and the concentration of the di-functional oligomer may be at least 20% by weight elative to the total weight of the composition.
