Abstract
Three-dimensional modeling method and apparatus for receiving information with respect to a three-dimensional object to be formed and for forming a three-dimensional physical object through the use of two building materials and a third filling material. The first building material is typically a photopolymer. The second building material has at least one of the following characteristics: elastomeric properties, engineering plastic thermoset properties, is suitable for lost wax casting, is impregnated with metallic materials, is impregnated with ceramic material, or is sinterable. The filling material is typically a support material to provide structural support to the model during building.
