A 3D printer user prints a part with PETG filament. Which property will the part most likely have?
AOpaque and dull surface
BBrittle and prone to cracking
CVery soft and melts easily
DFlexible and moisture resistant
Step-by-Step Solution
Solution:
Step 1: Recall PETG part properties
Printed PETG parts are known to be flexible and resist moisture well.
Step 2: Analyze options against PETG traits
Brittle and prone to cracking is false because PETG is not brittle. Very soft and melts easily is incorrect as PETG is not very soft. Opaque and dull surface is wrong since PETG parts are shiny, not dull.
Final Answer:
Flexible and moisture resistant -> Option D
Quick Check:
PETG parts = flexible + moisture resistant = A [OK]
Quick Trick:PETG parts resist moisture and flex, not crack or dull [OK]
Common Mistakes:
MISTAKES
Confusing PETG with brittle plastics
Assuming PETG parts are soft or melt easily
Thinking PETG parts have dull surfaces
