Title: Identify computer-driven additive and subtractive manufacturing processes.
Course: Materials and Processes Technology (13052-18) > Section: Exploring Computer-Driven Additive and Subtractive Manufacturing

Identification should include at least one additive process and one subtractive process:

- three-dimensional (3D) printing (e.g., fused-deposition modeling, stereo-lithography)
- computer numerical controlled (CNC) machining
- laser engraving/cutting.

Process/Skill Questions:

- What are examples of other processes one might consider additive or subtractive methods?
- Which method is better for producing an object? What are .stl and .obj files?
- What are the advantages of an additive or subtractive process?
- What are the different polymers used in 3D printing, and for what applications are they used?
- What determines whether an object should be produced with additive or subtractive manufacturing?
- How is the thermal separation process used in optical laser engraving/cutting?
