MATERIAL / PETG
PETG: the honest default.
PETG bends before it snaps, tolerates moisture and prints reliably on the Neptune 4. It is our default candidate for frames that will fly after review.
Pros
Tough, slightly flexible, weather-tolerant.
Cons
Heavier and less stiff than carbon plate.
Verdict
A practical starting material, still reviewed per design.

QUESTIONS
Will PETG break in a crash?
It can. It tends to bend first, and arms are reprintable.
