What is SpoolPrices?

SpoolPrices helps you find the cheapest 3D printing filament and resin by comparing prices across retailers and sorting by price per unit. Whether you're looking for PLA, PETG, ABS, or UV resin, we make it easy to compare costs and find the best deal. We track over 3,400 products across 12+ retailers, with prices checked every 2 hours and new products discovered automatically every 4 hours.

How It Works

  1. 1
    We aggregate prices from retailers. Our automated scraper checks prices across Amazon, Bambu Lab, Polymaker, Overture, and more — every 6 hours around the clock.
  2. 2
    We normalize to $/kg and $/L for fair comparison. A 2 kg spool at $40 is a better deal than a 1 kg spool at $22. We do that math for you so you can sort by true cost per unit.
  3. 3
    We track price history to show trends and deals. Every check is stored so you can see whether today's price is a true low, an average, or inflated. The Deals page surfaces the most recent price drops automatically.

Frequently Asked Questions

How often are prices updated?
Every 2 hours via automated checks. Our background worker runs 12 times a day, updating prices and flagging any significant drops. The "Checked" timestamp on each product card shows you exactly when that listing was last verified.
Do you earn a commission on purchases?
Yes, we earn a small commission through affiliate links — at no extra cost to you. When you click a "Buy Now" link and make a purchase, we receive a small percentage of the sale from the retailer. This is how we keep the lights on. The prices you see are the same as going directly to the retailer.
Is this site free to use?
Yes, completely free. No account required, no paywalled features. We're supported by the affiliate commissions described above, which lets us offer price comparison and price alerts without charging users anything.
