    • An additive building method for building a plurality of layers to form a build stack is provided. The method comprises creating a variable potential difference between a conducting element at a first voltage potential and an ion source at a second voltage potential, and creating an electric field between the conducting element and the ion source. The electric field passes through the build stack to a nearest surface of the build stack which is nearest a transfer medium. The method further comprises accumulating electric charge (Q) from the ion source on the nearest surface of the build stack, and transferring deposition material from a transfer medium onto the nearest surface. The strength of the field at the nearest surface of the build stack is controlled in order to cause a homogenous transfer of the deposition material on to the nearest surface.

    • A model such as a sacrificial casting pattern or core can be rapidly and inexpensively produced by lamination of cellular structure sheet material e.g., polystyrene foam. The polystyrene sheet (23) may be roller fed (20) onto a vertically adjustable platform (11) for cutting e.g., by a laser (18) to provide at least one cut out portion of required contour according to a predetermined control program. The cut out portion is also treated with adhesive such as by a hot melt spray applicator (19) and the platform (11) is lowered to permit further feed of sheet material (23) over the underlying cut out. The platform (11) is then raised for adhesion of the cut out to the underside of the further sheet material (23) and to support the latter for cutting. This operation is repeated until the model is completed. Apertured scrap sheet material passes from the platform preferably onto a take-off roller (21). The laser (18) and adhesive applicator means (19) are shown carried by carriage means (15, 17) on a gantry (13) for orthogonal movement in two directions (14, 16) to provide their coordinated positioning movement according to the predetermined program.
