Filament prices move a lot, and “sale” banners don’t always mean much. This page checks each brand’s own store every morning and logs the price per kilogram, so you can see what a spool normally costs and whether today’s price is actually low.
How to read it: the price shown is the brand’s own store price for a 1kg, 1.75mm spool. Amazon prices often differ and change through the day, so use the Amazon button to check yours. A Deal tag means the price is on sale or at least 10% under its 90-day typical price.

The default. Easy to print, stiff, cheap. Softens around 55–60°C, so keep it out of hot cars. Full PLA guide →

How this works
- Every morning a script checks each brand's own online store for a 1kg, 1.75mm spool and records the price per kg.
- 90-day range is the lowest and highest store price seen in the last 90 days. Deal means the store has it marked down, or it's at least 10% under its typical price. 90-day low needs two weeks of history before it shows.
- Amazon prices aren't listed because they change through the day — tap the Amazon button to see yours. Amazon links are affiliate links; buying through them supports the site at no extra cost to you.
- Shipping, tax, and color differences aren't included. Some colors cost more.
