A file is prepared with a very low infill percentage. What is the most likely effect on the printed object's strength?
AThe object will be very strong
BThe object will have a shiny surface
CThe object will be heavier
DThe object will be weak and fragile
Step-by-Step Solution
Solution:

  1. Step 1: Understand infill percentage meaning

    Infill percentage controls how much material fills the inside of the print.

  2. Step 2: Connect low infill to object strength

    Low infill means less material inside, making the object weaker and more fragile.

  3. Final Answer:

    The object will be weak and fragile -> Option D

  4. Quick Check:

    Low infill reduces strength = D [OK]
Quick Trick: Less infill means weaker prints [OK]
Common Mistakes:
MISTAKES
  • Assuming low infill makes object heavier
  • Thinking infill affects surface shine
  • Believing low infill increases strength
