Abstract: Method and kits for handling an aqueous waste solution or dispersion obtained upon removing a water-miscible support material from a three-dimensional object during additive manufacturing of the object, and additive manufacturing processes utilizing same are provided. The methods and kits utilize a super absorbent polymeric material to convert the liquid waste solution to a solid or semi-solid composition.

Abstract: A support material formulation for use in additive manufacturing of a three-dimensional object, which, when hardened, is soluble upon immersion in water, is provided. The formulation includes a hydrophilic curable mono-functional material; a polyol (e.g., a branched polyol) having a molecular weight lower than 1,000, or lower than 800 grams/mol; and a polyester material having a molecular weight higher than 400, or higher than 500, grams/mol. Additive manufacturing using the disclosed formulation and objects made thereby are also provided.
