A slicer shows no supports added despite model having steep overhangs. What could be a reason related to the overhang angle threshold?
AThe layer height is too large
BThe threshold is set too high, above the steepest overhang angle
CThe printer nozzle temperature is too low
DThe threshold is set too low, below the smallest overhang angle
Step-by-Step Solution
Solution:
  1. Step 1: Analyze threshold effect on support generation

    If threshold is higher than any overhang angle, no supports are triggered.
  2. Step 2: Relate to problem

    No supports despite steep overhangs means threshold is set too high.
  3. Final Answer:

    The threshold is set too high, above the steepest overhang angle -> Option B
  4. Quick Check:

    High threshold = No supports added [OK]
Quick Trick: High threshold disables supports for steep angles [OK]
Common Mistakes:
  • Blaming temperature or layer height
  • Thinking low threshold causes no supports
