Beschreibung
Zusammenfassung:	Formulations usable as support material in additive manufacturing such as 3D inkjet printing and which feature a viscosity of no more than 50 cPs at 35° C., are provided. The formulations are composed of at least one hydrophilic curable material which provides, when hardened, a material that is dissolvable or swellable in an aqueous solution; and at least one non-curable material that is capable of being swelled by said hardened material formed of said at least one curable material. Additive manufacturing processes utilizing these formulations and objects obtained thereby are also provided.
