Rapid Prototyping question paper:

PART A — (10 × 2 = 20 Marks)
1. List any four advantages of RP in product design and development.
2. How does digital prototyping differ from virtual prototyping?
3. What is called road width in fusion deposition modeling?
4. Discuss any four limitations of laminated object manufacturing.
5. Describe ‘Net shaped’’ manufacturing.
6. What is meant by ‘beam energy’ in electron beam melting? How is it controlled?
