Where to Buy 3D Printer Filament

The short answer

For standard PLA and PETG, the lowest prices are almost always a brand's own store or its official AliExpress storefront, particularly on 3-10kg bundles. For engineering materials (Nylon, PC, carbon fiber), European buyers get the best combination of price and selection at specialist stores like 3DJake, while US buyers often end up choosing between Amazon and buying direct from Polymaker or a US specialist. If you need filament tomorrow, Amazon is the answer and you pay a little extra for it.

The honest version of "where should I buy filament" is: it changes daily. Stores rotate sales constantly, and the store that was cheapest for white PLA last week is often beaten this week. That is the whole reason SpoolHound exists: the table below is generated from our live data and refreshes every day.

Buying direct from the brand

SUNLU, Elegoo, Anycubic, Creality, Polymaker and eSUN all run their own web stores, and for their own filament they are hard to beat. Multi-spool bundles are where the real savings live: 5kg and 10kg packs regularly land 30-60% below the single-spool market rate per kilogram. Brand stores also run near-constant coupon codes, which we track on the coupons page.

Two things to watch. First, each store only sells its own brand, so you are comparing within one catalog; check a cross-store view before committing to 5kg of anything. Second, regional sub-stores matter: a brand's EU store ships from EU warehouses with EUR pricing, while its global store may quote USD and ship slowly. SpoolHound tracks the regional stores separately for exactly this reason.

Specialist 3D printing stores

Stores like 3DJake (EU/UK) exist specifically for 3D printing, and it shows: hundreds of brands under one roof, real spec sheets, consistent stock, and strong house brands. Their everyday prices on commodity PLA sit slightly above the brand stores, but their sales are genuine and their engineering-material range (PC, PA, filled composites, Fillamentum, Prusament) is where they earn a bookmark.

In our price data, specialists most often win on the materials the giants barely stock: PCTG, ASA in unusual colours, glass-fiber composites, and premium European brands. If your print farm runs on more than PLA, you will end up ordering from one eventually.

Amazon

Amazon is where most people start, and for one good reason: the spool arrives tomorrow. The same SUNLU or Elegoo spool typically costs more there than at the brand's own store, and multi-kg bundle pricing is rare. Treat Amazon as the convenience option: unbeatable when a print job is blocked on an empty spool, rarely the best value for a planned restock.

One habit worth building: check the per-kg maths on Amazon listings. Sponsored placements and 500g spools priced like 1kg spools make the search results a minefield. We list Amazon products alongside every other retailer so the comparison is apples to apples.

AliExpress

The lowest per-kg prices in our entire dataset are usually official brand stores on AliExpress: JAYO (SUNLU's budget line), Kingroon, Eryone and SUNLU itself. Multicolour 5kg and 10kg packs there regularly bottom out the market. The trade-offs are real: shipping takes one to three weeks, spools occasionally arrive dusty or loosely wound, and disputes take patience.

The rules that keep it reliable: buy from the brand's official store on the platform rather than random resellers, check the per-kg price against the market (our listings do this automatically), and treat multi-week shipping as part of the price. For planned bulk buying it is excellent; for "I need filament this week" it is the wrong tool.

Buying filament in a store near you

The honest version: physical retail is the weakest way to buy filament in 2026, with one big exception. Micro Center (US) is the real deal, with a full filament aisle and their house-brand Inland spools priced to compete with online; if you live near one, it is the only store where walking in beats ordering. Beyond that it thins out fast: Best Buy has started stocking basic printers and a small PLA selection in some locations, Walmart and Home Depot list filament online but store shelves vary wildly, and craft chains like Hobby Lobby and Michaels generally stock 3D pen refills at most, not printer spools. Call before driving.

In Europe, dedicated in-store filament retail barely exists; electronics chains occasionally carry a spool or two of basic PLA at a hefty markup. The practical near-me play on both continents is the same: order online from a store that ships from your region so it arrives in a day or two. Every listing on our deals page shows the store's region, and the EU stores we track (3DJake, brand stores with EU warehouses) routinely deliver next-day.

What in-store buying costs you: selection (a shelf holds ten spools; the market holds 25,000+ listings) and price (shelf prices run 30-80% above the online market rate for the same spool). What it gets you: filament today. If a print is due tomorrow, that trade can be worth it; just know what the trade is.

How to actually find the deals

Whatever store you prefer, the method is the same: normalise to price per kilogram, compare across stores, and check whether a "sale" price actually beats the market median. That is mechanical work, so we automated it. The live deals table covers every listing we track, sorted by lowest per-kg price. The per-material pages show the current cheapest options: PLA, PETG, ABS, ASA, TPU, Nylon and the rest of the cheapest-prices hub. Today's deals surfaces the biggest current discounts, and coupon codes stack on top of several stores' prices.
