Abstract
A method of additive manufacturing of a three-dimensional object. The method comprises: sequentially dispensing and solidifying a plurality of layers comprising (i) a stack of model layers arranged in a configured pattern corresponding to the shape of the object and being made of a modeling material, (ii) a sacrificial structure having a stack of sacrificial layers made of an elastomeric material, and (iii) a stack of intermediate layers made of a support material having an elastic modulus less than the elastomeric material and being between the stack of model layers and the sacrificial structure; and applying a peeling force to the sacrificial structure (e.g., in dry environment) to remove the sacrificial structure, and to expose the stack of model layers and/or the stack of intermediate layers beneath the sacrificial structure.
