About
Find the real cheapest filament — at the amount you're actually buying.
FilaNexus compares 3D printing filament prices across brands and stores and ranks every offer by landed cost per kilogram, so a "cheap" spool and a 10 kg bundle can be compared fairly.
Why another price tracker?
Filament pricing in 2026 is dominated by multi-spool deals: "15% off 4 rolls", "$13.99 each when you buy 6", "$15 off orders over $150". Most trackers show one price per listing, which hides the best deals behind math you have to do yourself.
FilaNexus does that math. Tell it whether you're buying 1, 4, 6 or 10 kg and it re-ranks every offer using each store's tier discounts and coupon thresholds — and tells you when adding a couple more spools would drop your price per kilo.
How prices are calculated
- Net filament weight, not shipping weight. We read the real net kilograms from the product (1 kg, 4 × 1.1 kg, 10 kg bundle…) and never trust a third party's pre-computed $/kg.
- Quantity-aware discounts. Tier sales and minimum-order codes are applied at the quantity you pick.
- Compared against the market. Each offer is scored against the average price for that material, so you can see at a glance whether a "deal" is actually a deal.
- Timestamped. Every page shows when prices were collected. Prices change fast — always confirm the final price at the store before you buy.
Shipping and sales tax are not yet included in landed cost. Sign-in-only and member-only prices are shown separately and never used as a headline price.

How FilaNexus is funded
Some links to stores are affiliate links: if you buy through them, we may earn a small commission at no extra cost to you. Commissions never affect rankings — offers are always sorted by price. Read the full disclosure.
