A 3D printed part made from PLA is tested for heat resistance. What is the expected behavior when exposed to 80°C?
medium📝 Analysis Q4 of 15
Step-by-Step Solution
Solution:
Step 1: Understand PLA heat resistance
PLA softens around 60-70°C, so 80°C is above its softening point.Step 2: Predict behavior at 80°C
At 80°C, PLA will soften and may deform but not melt immediately.Final Answer:
The part will soften and deform -> Option BQuick Check:
PLA at 80°C = Softens and deforms [OK]
Quick Trick: PLA softens above 60°C, expect deformation at 80°C [OK]
Common Mistakes:
MISTAKES- Assuming PLA melts immediately
- Thinking PLA stays rigid at 80°C
