What is a common advantage of using PETG filament in 3D printing?
AIt is highly brittle and breaks easily
BIt is flexible and impact resistant
CIt melts at very low temperatures
DIt requires a heated chamber to print
Step-by-Step Solution
Solution:

  1. Step 1: Understand PETG's physical properties

    PETG is known for its flexibility and good impact resistance compared to other filaments.

  2. Step 2: Compare options with PETG traits

    Options A, B, and D do not match PETG's typical characteristics; it does not melt at very low temperatures, is not brittle, and does not require a heated chamber.

  3. Final Answer:

    It is flexible and impact resistant -> Option B

  4. Quick Check:

    Flexibility and impact resistance = C [OK]
Quick Trick: PETG is tough and flexible, unlike brittle plastics [OK]
Common Mistakes:
MISTAKES
  • Confusing PETG with PLA which is more brittle
  • Thinking PETG melts at very low temps
  • Assuming PETG needs a heated chamber
