Stop overpaying for
3D printer filament
Real prices from real retailers, normalised to price per kg. Filter by material, brand, color, weight, finish and actually compare what you're paying across stores.
Buying filament is weirdly annoying
You know what you want, but the price varies wildly depending on where you look. 1kg on one site, 3-pack on another, and good luck comparing without a spreadsheet.
Scattered across stores
Elegoo's site, 3DJake, Amazon, Overture's shop — every brand has their own storefront and pricing. Nobody aggregates it.
Is that actually a deal?
Every store has a "sale" running. We show the market median for each material so you can tell if a price is genuinely good or just marketing.
Apples vs oranges
1kg spool vs 3-pack vs 250g sample vs cardboard refill. You can't compare any of that without normalising to $/kg.
Death by browser tabs
You just wanted some PETG and now you've got 14 tabs open. We've all been there.
One page, every price
We pull product feeds from retailers, normalise everything to price per kg, and let you filter the lot.
We pull the feeds
Retailer product catalogues get pulled regularly and normalised — material, weight, color, finish, price per kg — all consistent.
You filter & sort
Material, color, finish, weight, diameter, brand, retailer. Sort by price per kg and the best value floats to the top.
Click through to buy
Found what you want? Click goes straight to the retailer's product page. No account, no checkout on our end.
We work for you, not for one marketplace
Many filament comparison tools only pull from Amazon or AliExpress — the two marketplaces with the biggest affiliate programs. That's not comparison shopping, that's picking a lane. We list every retailer we can legally list, whether they pay us a commission or not.
Paid or not, they're in
If a retailer sells filament and we can legally display their prices, they get listed. Many of the stores on SpoolHound earn us zero commission — we include them because that's sometimes where the best price is.
Direct relationships, not scraping
We pull feeds directly from affiliate networks (Impact, AWIN), manufacturer partnerships, and Shopify stores. Real SKUs, real prices, pulled daily.
No single point of failure
If a marketplace changes its affiliate terms tomorrow, we still have 40+ other retailers showing prices. Your best deal shouldn't depend on one company's policy.
What you get out of the box
Price per kg comparison
All prices normalised to cost per kilogram so 1kg, 3kg, and refill spools are directly comparable.
Granular filters
Material, color family, finish (matte, silk, marble…), weight, diameter, spool type, retailer, and more.
Market context
Every listing shows where its price sits relative to the IQR-trimmed median for that material and currency. Outliers don't skew it.

14 material guides covering print temps, bed adhesion, enclosure needs, post-processing, and when to actually pick one material over another.
