Match the additive manufacturing technique in Column I with its corresponding input material in Column II. Column I: P. Fused deposition modelling, Q. Laminated object manufacturing, R. Selective laser sintering Column II: 1. Photosensitive liquid resin, 2. Heat-fusible powder, 3. Filament of polymer, 4. Sheet of thermoplastic or green compacted metal sheet

1. P-3, Q-4, R-2
2. P-1, Q-2, R-4
3. P-2, Q-3, R-1
4. P-4, Q-1, R-4

Correct answer: P-3, Q-4, R-2

Solution

Fused deposition modelling uses a polymer filament, laminated object manufacturing uses sheets, and selective laser sintering uses heat-fusible powder. Therefore the correct matching is P-3, Q-4, R-2.
