Abstract

Methods for fabricating three-dimensional objects by 3D-inkjet printing technology are provided. The methods utilize curable materials that polymerize via ring-opening metathesis polymerization (ROMP) for fabricating the object, in combination with acid-activatable pre-catalyst and an acid generator activator. Kits containing modeling material formulations usable in the methods are also provided.
