Why is it important to control the cooling fan speed dynamically during 3D printing rather than running it at full speed all the time?
ATo reduce noise by running fan at low speed only
BTo save electricity by turning fan off completely
CBecause the fan overheats if run continuously
DTo prevent warping and improve layer adhesion
Step-by-Step Solution
Solution:
  1. Step 1: Understand effects of fan speed on print quality

    Running fan at full speed can cool layers too fast causing warping or poor adhesion between layers.
  2. Step 2: Identify why dynamic control helps

    Adjusting fan speed based on layer or print phase prevents defects and improves print strength.
  3. Final Answer:

    To prevent warping and improve layer adhesion -> Option D
  4. Quick Check:

    Dynamic fan control = Better print quality [OK]
Quick Trick: Adjust fan speed to balance cooling and adhesion [OK]
Common Mistakes:
  • Thinking fan is off to save power only
  • Assuming fan overheats if always on
  • Believing noise is main reason for control
