Filament Price Tracker monitors 14,934 active listings across 425 brands, updated every 4 hours and normalized to a true cost per kilogram so you can compare materials and spool sizes on a level playing field.
Every product has its own page with the current price, true cost per kilogram, and how it stacks up against the market average, plus a direct link to the best current deal, no account needed. We also track the gear that keeps filament printable, dryers, dry boxes, and storage, in the Dryers & Storage section.
Plus in-depth guides, news, and analysis on filament types, print settings, and the broader 3D printing market.
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 defining challenge isn't heat, it's adhesion: PP resists sticking to almost every common bed surface, so a dedicated build surface or adhesive is usually part of the setup.
We compare PP filament from 4 brands.
CHCKX is one of the filament brands we track, with 95 listings on the tracker spanning PETG, PLA, PCTG, and Nylon-GF, plus 10 more materials.
