About

filament.cool is an independent price comparison site for 3D printer filament. Every product goes in one table, normalized to price per kilogram, so a 750 g spool, a 1 kg spool, and a ten-spool bundle can be compared honestly. Because a cheap price per kilogram often means buying in bulk, you can filter by how much filament a listing commits you to.

Where the prices come from

Prices are collected from retailer listings and refreshed periodically, so a listed price can lag the retailer. The price on the retailer's page at checkout is always the one that applies.

How this site makes money

Buy links are affiliate links. If you click one and make a purchase, the retailer may pay filament.cool a commission at no extra cost to you. filament.cool participates in affiliate programs including the eBay Partner Network.

Commissions never affect the table: rows are sorted and filtered purely by the listed data, and there is no paid placement.
