Abstract: The present invention relates to a composition to form support materials for 3D (three dimensional) printing and the application of said composition in 3D printing process as well as the resultant 3D object. The present invention also provides a process of fabricating a three-dimensional object, comprising i) dispensing a build material that comprises a model material composition and a support material composition; ii) curing the layer dispensed in step i); iii) repeating step i) and ii) so as to sequentially form a plurality of layers in a configured pattern corresponding to the shape of the object; and iv) removing the support material from the build material.
