Problem
1. Why is orienting cylindrical holes vertically better than doing it horizontally for building a rapid prototype?
2. How does the slicing (layering) thickness affect the quality of rapid prototyping?
3. Describe the two types of support structures for prototyping.
4. List and describe the concepts of rapid prototyping.
5. Explain and sketch what is meant by deviation tolerance in triangulation. How does it affect the triangulation accuracy?
