Problem
1. Explain and sketch what is meant by angle tolerance in triangulation. How does it affect the triangulation accuracy?
2. List and describe the steps of the rapid prototyping process.
3. Research the stereolithography (SLA) technique. Submit a detailed report about how the technique works, the build and support structure material, the model slicing and orientation, the machine operation and how it builds the prototype, the pre-process operations, the post-process operations, and the cleanup and painting. Include a schematic of the SLA machine to show its operation mechanism including the laser operation, the vat, and the photopolymer.
