We track 1 SUNLU PP listings, with prices checked every 4 hours and normalized to a true cost per kilogram. Below is every listing, sorted by price per kg.
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.
Best for living hinges, snap fits and parts that must resist chemicals.
Based on Prusa guidance. See the nozzle types guide for brass vs hardened steel.
