A 3D print using nylon-carbon fiber composite shows weak bonding between layers. Which printer setting adjustment is most effective to improve layer adhesion?
AReduce the extrusion multiplier
BDecrease the printing speed drastically
CLower the bed temperature
DIncrease the printing temperature
Step-by-Step Solution
Solution:
  1. Step 1: Identify cause of poor layer adhesion

    Low printing temperature can cause insufficient melting and bonding.
  2. Step 2: Evaluate adjustments

    Increasing temperature improves layer fusion; lowering bed temp or extrusion multiplier worsens adhesion.
  3. Final Answer:

    Increase the printing temperature -> Option D
  4. Quick Check:

    Higher temp improves layer bonding in composites. [OK]
Quick Trick: Raise print temperature to fix layer adhesion [OK]
Common Mistakes:
MISTAKES
  • Reducing extrusion multiplier which lowers material flow
  • Lowering bed temperature which reduces adhesion
  • Assuming speed change alone fixes bonding
