CheapSpool: The Filament Pricing Aggregator Tracking 90+ Brands Across Three Regions

Filament pricing is messy. Brands run sales on their own storefronts but not on Amazon. Some colors only exist in one place. Prices change. Keeping track of this across even a handful of brands is a spreadsheet problem — CheapSpool is a direct solution to that.

What CheapSpool Does

CheapSpool.com is a price comparison aggregator specifically for 3D printer filament. It tracks 90+ brands across three markets — the US, Canada, and the UK — and updates daily.

The key design decision: it tracks both manufacturer storefronts and Amazon, because the best price on any given spool isn’t always in the same place. Sales and promotions run almost exclusively on manufacturer sites. But certain colors, spool sizes, and limited editions often appear only on Amazon. Tracking one without the other misses real savings opportunities.

Every “Buy Now” link goes directly to the brand’s own storefront or Amazon listing — no CheapSpool middleman in the purchase flow.

Affiliate Link Disclosure

The site uses some affiliate links, and the creator disclosed this explicitly when posting to r/BambuLab (with mod permission). Not all links are affiliate-linked — some are direct. The transparency here is worth noting as a baseline for how filament price comparison sites should operate.

Who It’s For

CheapSpool is most useful for:

High-volume printers who buy filament regularly and benefit from catching sales and price drops before placing multi-spool orders.

Multi-material setups — AMS users and multi-extruder configurations go through filament fast enough that the price delta across brands and storefronts compounds meaningfully over time.

Brand explorers comparing price-per-kg across the 90+ tracked brands, especially when trying a new material type where brand differences in price are significant.

UK and Canadian printers, who have fewer native price comparison tools than US-based users.

Caveats

The site tracks price, not print quality. CheapSpool doesn’t distinguish between well-regarded brands like Polymaker, Bambu, or Prusament and lower-quality alternatives — it surfaces price, and you supply the quality judgment. For any brand you’re evaluating for the first time, check community reviews before buying based on price alone.

Coverage is also limited to the tracked regions. European brands not selling into the US, CA, or UK markets won’t appear.
