A method of fabricating a three dimensional model from a composite model formed by a plurality of layers. The composite model comprises at least one shell material encasing and enclosing a build material. The method comprises the steps of (1) depositing a build layer of the build material onto a preceding layer, (2) removing a selected area of the build material from the deposited build layer; (3) depositing the shell material in any removed selected area of the build material; and (4) reducing the build layer to a desired final thickness for supporting a next build layer. Then repeatedly repeating steps (1) through (4) for each build layer until the composite model is completed. Finally, the undesired extraneous material, and possibly the shell, are removed to obtain the final model.
A method of fabricating a three dimensional model from a composite model formed by a plurality of layers with the composite model comprising at least one shell material encasing and enclosing a build material, the method comprising the steps of:
An apparatus for fabricating a three dimensional model from a composite model formed by a plurality of layers with the composite model comprising at least one shell material encasing and enclosing a build material, the apparatus comprising a rapid deposition spray for depositing the build material on a build layer, a machining device for removing selected areas of the build area, a rapid deposition shell material dispensing device for dispensing shell material into the selected removal areas, and a material reducing device for reducing a height of the build layer to a final thickness for supporting a subsequent build layer;
