30 PERIODS

PRACTICAL EXERCISES:	30 PERIODS

1. Study the interface and basic tools in the CAD software.
2. Study 3D printer(s) including print heads, build envelope, materials used and related support removal system(s).
3. Review of geometry terms of a 3D mesh.
4. Commands for moving from 2D to 3D.
5. Advanced CAD commands to navigate models in 3D space.
6. Design any four everyday objects
Refer to web sites like Thingiverse, Shapeways and GitFab to design four everyday objects that utilize the advantages of 3D printing
Choose four models from a sharing site like Thingiverse, Shapeways or Gitfab.
  a. Improve upon a file and make it your own. Some ideas include:
     • Redesign it with a specific user in mind
     • Redesign it for a slightly different purpose
     • Improve the look of the product
7. Use the CAM software to prepare files for 3D printing.
8. Manipulate machine movement and material layering.
9. Repair a 3D mesh using
  a) Freeware utilities: Autodesk MeshMixer (http://goo.gl/x5nhYc), MeshLab (http://goo.gl/fgztLl) or Netfabb Basic or Cloud Service (http://goo.gl/Q1P47a)
  b) Freeware tool tutorials: Netfabb Basic or Cloud Service (http://goo.gl/Q1P47a), Netfabb and MeshLab (http://goo.gl/WPOVec)
  c) Professional tools: Magics or Netfabb
    Equipment : one 3D printer for every 10-15 students
