Novel support material formulations, characterized as providing a cured support material with improved dissolution rate, while maintaining sufficient mechanical strength, are disclosed. The formulations comprise a water-miscible non-curable polymer, a first water-miscible, curable material and a second, water-miscible material that is selected capable of interfering with intermolecular interactions between polymeric chains formed upon exposing the first water-miscible material to curing energy. Methods of fabricating a three-dimensional object, and a three-dimensional object fabricated thereby are also disclosed.

Support material formulation and additive manufacturing processes employing same

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) in combination with toughening agents for fabricating the object. Systems suitable for performing these methods and kits containing modeling material formulations usable in the methods are also provided.

Three-dimensional inkjet printing using ring-opening metathesis polymerization

Methods for fabricating three-dimensional objects by 3D-inkjet printing technology are provided. The methods utilize a combination of curable materials that polymerize via ring-opening metathesis polymerization (ROMP) and curable materials that polymerize via free-radical polymerization (FRP) for fabricating the object. Systems suitable for performing these methods, kits containing modeling material formulations usable in the methods and objects obtained thereby are also provided.

Three-dimensional printing combining ring-opening metathesis polymerization and free radical polymerization

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.
