The Stratasys Fused Deposition Modeling (FDM) system is a rapid prototyping technology which creates three-dimensional therm0 plastic models using an industry standard Computer Aided Design (CAD) stl-formatted file. The model's .stl tile is pre-processed by creating slice layers equal to the build layer thickness. These sliced layers are used to create an .sml-build file, which is transferred to the FDM machine. The model is fabricated on a Styrofoam foundation tray mounted on a Z-axis platform assembly that increments downward during the build process. A thermoplastic extruding device moves in two axes to complete each layer. This process of successively fusing each layer to the previous one continues until the model fabrication process is completed. The Styrofoam base and finished prototype are removed from the machine after fusing (or extruding) the last layer.
