If the first layer speed is set to 20 mm/s and the first layer height is 0.2 mm, what is the likely effect on adhesion?
AGood adhesion due to balanced speed and height
BPoor adhesion because speed is too high
CPoor adhesion because height is too low
DNo effect on adhesion
Step-by-Step Solution
Solution:
  1. Step 1: Analyze first layer speed

    20 mm/s is a moderate speed that allows filament to stick well without dragging.
  2. Step 2: Analyze first layer height

    0.2 mm is a common height that provides good bed contact.
  3. Final Answer:

    Good adhesion due to balanced speed and height -> Option A
  4. Quick Check:

    Moderate speed + 0.2 mm height = good adhesion [OK]
Quick Trick: Moderate speed and height improve first layer adhesion [OK]
Common Mistakes:
  • Assuming any speed above 15 mm/s is bad
  • Thinking 0.2 mm height is too thin for adhesion
