Frequently Asked Questions

How often are prices updated?

Prices are synced from retailer feeds every day at 3am UTC. Most retailers update their feeds hourly, so our data is typically less than 24 hours old.

Which retailers do you track?

We track Elegoo, Flashforge, 3DJake, SUNLU, Overture, Anycubic, Eryone, and Chitu Systems across 9 regions (USA, UK, DE, FR, IT, ES, AU, CA, EU). Amazon product listings are shown but prices are pending API access.

What does price per kg mean?

Price per kilogram normalises the cost across different spool sizes (250g, 500g, 1kg, 3kg, etc.) so you can directly compare value regardless of packaging. A 500g spool at $12 and a 1kg spool at $22 are $24/kg and $22/kg respectively.
