A user sets 2 perimeters with a perimeter width of 0.5 mm but notices the wall thickness is not 1.0 mm as expected. What could be the issue?
AThe printer's actual extrusion width differs from the set perimeter width
BThe number of perimeters was set to 3 instead of 2
CThe layer height is too high
DThe print speed is too slow
Step-by-Step Solution
Solution:
  1. Step 1: Understand expected wall thickness

    With 2 perimeters and 0.5 mm width, wall thickness should be 1.0 mm.
  2. Step 2: Identify why actual thickness differs

    The actual extrusion width may differ from the set perimeter width, causing mismatch.
  3. Final Answer:

    The printer's actual extrusion width differs from the set perimeter width -> Option A
  4. Quick Check:

    Extrusion width mismatch causes wall thickness error [OK]
Quick Trick: Check actual extrusion width, not just settings [OK]
Common Mistakes:
  • Assuming layer height affects wall thickness
  • Thinking print speed changes wall thickness
  • Miscounting number of perimeters
