Digitizing Objects

• Two main techniques: photogrammetry and LIDAR
  • Photogrammetry
  • LIDAR / 3d scanning (with laser)
    • ArTec scanner at NIS.

3D Scans into Rhino

Importing a 3D Scan

• Create a new file in Rhino and import a 3d scan
  • bunny.ply (3MB)
• Find the bunny and scale to an appropriate size.
  • Locate (Zoom eXtents), Rotate, Scale
  • Simplify Mesh (MeshReduce) if necessary

Prepping for 3DP

• Add a base
• Add a label (text objects as solids)
• Is it a closed object?
  • Mesh -> Repair Tools
• Save as STL.

Slicing for 3DP

• Download Prusa Slicer (DRIVERS & APPS)
• Load your STL file from the previous steps.
• Check scale, positioning.
• Select print parameters.
  • Material. Slicing. Support.
• Add multiple objects to a build.

Meshmixer

• Download Meshmixer
• Hacking things together with meshmixer.
• Exporting for 3DP (.STL)

Homework

• Exercise 5 DUE Thursday September 30, 9pm
• Concept for Project 1. 2 paragraphs on Canvas.

Office Hours

• Wednesday afternoon 9/29 (after 1pm)
