Abstract

Mold preparation method including the steps, which consist of forming a layer of a model separating agent on the shaping surface of a model, arranging a layer of a protective film on said layer located on the shaping surface, arranging a filler material on the opposite side of said protective film, bringing said protective film into intimate contact with the filler material by aspiration by making a vacuum in the space surrounded by the particles of filler material in order to produce in it a negative pressure or less than atmospheric pressure and separate said model from said protection film to form a cavity.
