PET

Polyethylene Terephthalate

Related to PETG but less flexible and more dimensionally stable.

Ease of use: Very hard

This filament is demanding to print. Worth watching: it can be a little moisture-sensitive.

Things to watch

Picks up moisture over time, store it with desiccant
Can be brittle, may crack under sharp impact

Strengths

Solid strength for everyday parts
Stiff and rigid, resists flexing
