About PP Filament
PP (polypropylene) is a tough, chemical- and fatigue-resistant plastic best known for living hinges: its semi-crystalline structure lets a thin printed section flex thousands of times without cracking, unlike the brittle snap of PLA. Its main printing challenge is bed adhesion: PP resists sticking to almost every common bed surface, so a dedicated build surface or adhesive is usually part of the setup.
Nozzle temp 220-250°C
Nozzle type Brass or hardened steel
Bed 60-100°C (PP tape or PP sheet)
