Software: PropCAD®
Scope of work:
- Compilation of technical information
- Analysis of point cloud measured by scanner
- Adjustment of the surface of the propeller to the point cloud
- Generation of 3D geometry
Results:
After receiving the propeller at VICUSdt facilities, the surface was cleaned and prepared for scanning. Due to its size, the propeller was braced during the acquisition of the spatial points that define the measured surface.
The geometric data of these spatial points were processed using the ScanConverter utility from HydroComp PropCad program. After internal filtering, the surface defining the propeller blade was generated. From this dataset, all distributions of the different geometrical parameters that define the propeller were obtained—data necessary if a 2D drawing had to be made.
From scanning to 3D CAD geometry
From the point cloud and surface definition, a complete 3D CAD geometry of the propeller was generated. This model was then exported to a format compatible with 3D printing, in this case Parasolid (*.x_t).
Finally, the 3D propeller printed was successfully manufactured and installed on the yacht. Sea trials confirmed correct operation at maximum power without any issues, validating the accuracy and efficiency of the scanning and printing process.
