Step-by-Step Solution
Solution:
Step 1: Understand layer thickness and object height
The object height is 10 mm, and each layer is 0.2 mm thick.Step 2: Calculate number of layers
Divide total height by layer thickness: 10 mm ÷ 0.2 mm = 50 layers.Step 3: Recheck nozzle size relevance
Nozzle size affects width, not layer height, so it doesn't change layer count.Final Answer:
50 layers -> Option BQuick Check:
10 ÷ 0.2 = 50 layers [OK]
Quick Trick: Divide height by layer thickness for layers count [OK]
Common Mistakes:
MISTAKES- Using nozzle size to calculate layers
- Multiplying instead of dividing height by layer thickness
- Confusing layer thickness with nozzle diameter
