Attorney, Agent or FirmInternational ClassesB62D 65/00 (20060101)G09B 25/00 (20060101) AbstractA method of making hard surface prototypes or styling concept models by assembling a contoured polystyrene foam pattern and applying an epoxy clay-like material in two steps to replace the surface of the polystyrene foam pattern. The polystyrene foam pattern is first assembled from blocks cut out to design drawing specifications. The pattern is then shaped to the design contour. The surface of the pattern is then grooved and the grooves filled with the epoxy clay. The remainder of the pattern surface is then removed and replaced by more epoxy clay which is then sanded and finished with paint and suitable trim pieces. | |
