  • Seamless model and method of making a seamless model
    Patent number: 8580869
    Abstract: The present disclosure relates to a seamless model free of bond lines made by a method which includes the steps of providing a substructure having an exposed outer surface, applying a modeling paste to the outer surface of the substructure in the form of a continuous layer, curing the continuous layer of applied modeling paste, and machining said cured layer of modeling paste to the desired contour to form the seamless model. The modeling paste may be a mechanically frothed syntactic foam prepared by injecting inert gas with mechanical stirring into either a formed froth-forming polyurethane or epoxy composition containing microballoons.
    Type: Grant

  • Seamless model and method of making a seamless model
    Patent number: 8182876
    Abstract: The invention relates to a seamless model free of bond lines and to a method of making same. The method includes the sequential steps of providing a substructure having an exposed outer surface, applying a modeling paste to the outer surface of the substructure in the form of a continuous layer, curing the continuous layer of applied modeling paste, and machining said cured layer of modeling paste to the desired contour. The modeling paste of the invention is a mechanically frothed syntactic foam prepared by injecting inert gas with mechanical stirring into either a formed froth-forming composition, which is preferably a polyurethane or epoxy froth-forming composition containing microballoons.
