Which of the following is a key property of PETG material used in 3D printing?
AIt is strong and flexible
BIt melts at very low temperatures
CIt is very brittle
DIt produces a strong odor when printed
Step-by-Step Solution
Solution:

  1. Step 1: Recall PETG properties

    PETG is known for being strong and flexible, making it popular for durable prints.
