medium📝 Analysis Q7 of 15
3D Printing - Support Structures
Why might a support pattern like concentric cause problems in prints with overhangs?
ABecause it changes the color of the print
BBecause it uses too much material and slows printing
CBecause it may not provide enough support under overhangs
DBecause it increases print bed temperature
Step-by-Step Solution
Solution:

  1. Step 1: Understand concentric pattern shape

    Concentric supports follow the shape outline, which may leave gaps under overhangs.

  2. Step 2: Assess impact on overhang support

    Insufficient support under overhangs can cause print defects or failures.

  3. Final Answer:

    Because it may not provide enough support under overhangs -> Option C

  4. Quick Check:

    Concentric pattern may lack overhang support [OK]
Quick Trick: Concentric may miss support under overhangs [OK]
Common Mistakes:
  • Confusing material use with support quality
  • Thinking pattern changes print color
  • Assuming bed temperature is affected
