Interfacing geometric model data with rapid prototyping systems

The direct slicing of CAD models created in CADDS V to generate geometric d ata for rapid prototyping using fused feposition modeling technique (FDM) i s presented in this paper. The report file from an explicit model is access ed for obtaining model data. Algorithms have been developed for determining the volumes of model material as well as support materials. New algorithms have been developed for filling the sheet solid. A simulation module has b een developed to verify whether the filling is correctly done. Example of a model is manufactured using this approach is also presented in this paper.
