Claim Text:
1. A method of manufacturing a three-dimensional object comprising: sequentially depositing layers of a thermoplastic polymer composition mixture comprising a polymer phase and a particulate filler phase, said polymer phase comprising at least one thermoplastic polymer and said particulate filler phase being in sufficient quantity so as to render the three-dimensional object so formed to a specific gravity above 2.5; wherein said particulate filler phase comprises a material selected from the group consisting of tungsten, stainless steel alloys, copper, bismuth oxides, bismuth subcarbonates, bismuth oxychlorides, barium sulfates, barium titanates, and mixtures thereof; and wherein the method is a fused deposition modeling (FOM) additive process.
