We track 3D printer filament prices on PLA, PLA+, PETG, PCTG, and 60+ more materials from 90+ brands, including Bambu Lab, Hatchbox, Polymaker, Sunlu, and more. Updated daily across three markets: United States, Canada and United Kingdom.
No tab-hopping. We track manufacturer storefronts and Amazon because the best price isn't always in the same place, since sales and promos run almost exclusively on manufacturer sites, while some colors or spool sizes only appear on Amazon. One search, every option.
Prices/availability are pulled directly from brand storefronts and Amazon throughout the day to ensure the information you see is in parity with the manufacturer's site
No. CheapSpool is a price comparison tracker. Every Buy Now link takes you directly to the brand's own store or Amazon listing. We earn a small affiliate commission on some purchases, which keeps the tracker free.
Not always. Budget brands can deliver decent results on PLA and PETG, but tolerance consistency varies. Our articles and filament guide cover what each brand is actually good for.
PLA is easier to print, cheaper, and produces a cleaner surface finish, but softens around 60°C and is brittle under impact. PETG is tougher, more heat-resistant (up to ~80°C), and handles moisture better, but strings more. See the filament guide for a full comparison.
It depends on what you're printing. PLA for indoor models and prototypes, PETG for functional parts, ASA or ABS for outdoor or high-heat use, TPU for flexible parts. Our filament guide covers 60+ materials with print settings and use cases.
