A 3D printed part using nylon and carbon fiber composite is cracking during printing. What is the most likely cause?
AUsing too much cooling fan speed
BPrinter nozzle is too large
CPrinting speed is too slow
DPrinting temperature is too low
Step-by-Step Solution
Solution:
  1. Step 1: Understand cracking causes

    Low temperature can cause poor layer bonding and cracks.
  2. Step 2: Evaluate options

    Nozzle size and speed less likely cause cracks; too much cooling can cause warping but cracking is mainly from low temp.
  3. Final Answer:

    Printing temperature is too low -> Option D
  4. Quick Check:

    Low temp causes cracks [OK]
Quick Trick: Check temperature first if cracks appear [OK]
Common Mistakes:
MISTAKES
  • Blaming nozzle size for cracks
  • Assuming slow speed causes cracking
  • Ignoring temperature effects
