Additive manufacturing (AM) or additive layer manufacturing (ALM) is the industrial production name for 3D printing, a computer controlled process that creates three dimensional objects by depositing materials, usually in layers. 

3D Sketching

This lesson introduces you to 3D sketching and describes the following concepts:

• Sketching relative to coordinate systems

• Dimensioning in 3D space

• Mirroring features

Roller Chain Modeling Challenge

Time - 4 Class Periods

Challenge Objective - 3D model a roller chain link of your own design and print a series of five links without print supports.  When completed, the link should move as a roller-type chain.

Criteria

• Must be designed in SolidWorks

• Prepared in a slicer for additive manufacturing

• 3D printed in PLA filament

• An individual link cannot take up more space than 20mm²

• Test prints (no more than two links) are required before full prints (no more than 5 links)

• No slicer-generated supports allowed
