We went through every filament deal in Amazon’s Prime Day feed and kept only the ones where the sale price is at or below the lowest price seen anywhere on Amazon in all of 2026.
🗓 Deals Live: June 23 – June 27, 2026 · Prime Members Only
Prime Day is the best stocking-up event of the year for filament. Brands like ELEGOO, FLASHFORGE, Creality, and Polymaker rarely go this low outside of Black Friday — and some of these deals are the cheapest these spools have ever been in 2026.
We’ve split this list into three sections: PLA & PLA+ (the everyday workhorse filaments), PETG & specialty (for functional and decorative prints), and flexible TPU (for grips, gaskets, and bendable parts). Every product includes the exact deal price, list price, and how far it sits below the 2026 YTD low.
📌 How we picked these deals We cross-referenced every filament product in Amazon’s Prime Day Creator Connections feed against its year-to-date price history. Products are marked ↓ Below YTD where the deal price beats the 2026 low, or = Matches YTD where it ties it. No product that was already at this price for weeks made the cut.

- Filament deals sell out faster than printer deals. If something is in your cart, don’t wait until June 27.

Frequently Asked Questions
When do Prime Day 2026 filament deals go live?
All filament deals on this list go live on June 23, 2026 at 5:30 AM IST and expire June 27, 2026 at 5:29 AM IST. They are available to Amazon Prime members only.
What’s the difference between PLA and PLA+?
Standard PLA is easy to print and great for visual models but can be brittle. PLA+ uses a modified formula that adds flexibility and impact resistance while remaining just as easy to print. For functional parts, PLA+ is the better choice.
Is Prime Day a good time to stock up on filament?
Yes — along with Black Friday, Prime Day is one of only two annual windows where major filament brands consistently hit their price floors. Several deals on this list match or beat the cheapest prices seen anywhere in 2026.
Can I use these filaments with any 3D printer?
Most PLA and PLA+ filaments on this list are compatible with virtually any FDM printer. PETG requires slightly higher temperatures (230–250°C nozzle, 70–85°C bed). TPU works best with direct drive extruders. Carbon fiber variants need a hardened steel nozzle to prevent wear.
Which filament deal has the biggest discount?
The FLASHFORGE Rapid PETG Metallic Bright Gold is technically the biggest percentage markdown at 48% off list price. For real-world savings vs. recent Amazon pricing, the FLASHFORGE Rapid PLA Ruby Red (46% off, also below YTD low) is the strongest deal overall.
What is “YTD low” and why does it matter?
YTD low is the lowest price a product has sold for on Amazon in 2026 so far. A deal that matches or beats the YTD low is genuinely the best price of the year — not just a markdown from an inflated list price. We only included products that meet this bar.
