Abstract: A method of additive manufacturing for producing a 2-part mold suitable for use in injection molding, comprises: obtaining a computerized 3D representation of a 2-part mold (3D mold); delimiting one or more regions within the 3D mold; assigning a material or a combination of materials to each delimited region which is different from different from materials used in other delimited regions or outside the delimited regions; and producing the 2-part mold by additive manufacturing; wherein the delimiting comprises carrying out an offset from a surface of the 3D mold which is intended to be in contact with injected material, and wherein the offset is carried out within the solid part of the 3D mold.
