- 2. Introduction3D Solid Laser Modeling is a modern technique used to accurately represent physical objects into the virtual world.Required ToolsHD Laser (Picza3D Laser Scanner)Image Processing Technology (Dr. Picza3)CAD Software (SolidWorks)
- 3. What is Laser Modeling?Creation of point cloud system representing a geometric surface with a laser beam.Records distance values to the surface within the scanners field of view.The object is then recreated in a “reconstruction” software package.
- 4. PICZA 3D Laser ScannerLocated in the Bell Hall 4th Floor IE Laboratory
- 6. Data AcquisitionData from laser transmitted to computer via USB.Able to manipulate scan parameters.Resolution QualityLaser Beam PitchRotation AngleObject Height
- 8. Data ConversionAfter reconstruction complete, save file format as “.STL”.This allows for post- processing of data in desired CAD program.
- 9. Post ProcessingUsed to eliminate scanning errorsIncreases accuracy of scanEnables reconstructed object to be utilized in CAE platform.
- 10. Post Processing Phase 1:Importing Scans into SolidWorks
- 11. Enable SolidWorks Add-In “ScanTo3D”Step 1 of 14
- 12. Open File as “Mesh”Step 2 of 14
- 13. View Mesh of PartStep 3 of 14
- 14. Select “Mesh Prep Wizard”Step 4 of 14
- 15. Select the Mesh you Wish to ProcessStep 5 of 14
- 16. Select “No Orientation”Step 6 of 14
- 17. Use Tools to Select and Delete Excess MaterialStep 7 of 14
- 18. Hand Select Excess Material and RemoveStep 8 of 14
- 19. Simplify Mesh SizeStep 9 of 14
- 20. Change Global SmoothnessStep 10 of 14
- 21. Increase Boundary SmoothnessStep 11 of 14BeforeAfter
- 22. Fill Model Holes (Pre-Implementation)Step 12 of 14
- 23. Fill Model Holes (Post-Implementation)
- 24. Create Model SurfaceStep 13 of 14
- 25. Delete Surface ErrorsStep 14 of 14
- 27. Post Processing Phase 2:Post Processing in SolidWorks
- 28. Object is Broken Into Mesh Sections
- 30. Create Surface from Hole Edges
- 40. Finalize Desired Surface Fills
- 42. What are the Benefits?Save time modeling complex components.Accurate representation of surfaces impossible to achieve with current solid modeling technology.Wood grains, bumpy surfaces, curves, grooves, etc.Allows for better analysis in CAE platforms.Motion simulation, fluid flow analysis, FEA analysis, etc.
- 43. What are the Drawbacks?High resolution scans mean large files.Usually post processing required.Requires high end technologyRAMRAM limits number of data points that can be created.Processor SpeedDetermines how long it will take to create surface generation.
