Figure 60: Stratasys rDM 2000 After a propeller solid model is created in SolidWorks, the propeller geometry can be exported as an .STL file. When an .STL file is input into Quickslice Version 6.0, a model structure is automatically created for the file, shown in Figure 61. 100
Figure 61: Sereenshot of Propeller Blade Generated by Quicksliee Software The FOM printable file ean generate both a total volume calculation and a completion time estimate before the production. The following lists arc the steps for the fabrication using Stratasys FOM 2000. Start Quickslicc and open the .STL file. Choose tips ofmaterial extrusion nozzle. Small tip can provide higher strength and smooth surface finish, however; it will take much more time and material. Because the blades ofa propeller arc thin and need to support high stress, small tip is preferred for propeller fabrication. Set up the orientation ofa model in Quickslice. The two options of moving and rotating can be used for the orientation and make sure the model is in the 101
