How to Choose Filament on Sale
- PLA, PLA+ or PETG: PLA is the easiest and cheapest. PLA+ is listed as tougher. PETG is the tougher functional option but usually needs hotter, more careful settings.
- Look, not just strength: Silk PLA is shiny, matte PLA is soft and flat, and gradient or tricolor spools change color along the print.
- Spool size and bundles: 1kg spools are the best value for colors you use often. 250g bundles are better for testing colors, but cost more per ounce.
- Price per ounce: Compare Amazon’s per-ounce figure, not the headline price. The ANYCUBIC 10KG bundle lists $0.28 per ounce, while the SUNLU and Creality PLA spools list $0.32.
- Diameter and compatibility: Every filament here is 1.75mm, which fits most FDM printers. Check your printer supports PETG before buying it.
- Keep it dry: Store open spools sealed with desiccant, especially PETG.

Should You Buy Filament Now or Wait for Black Friday?
Buy now if a spool or bundle you have already picked hits a price you like. Amazon’s October event ends tonight, and popular colors can sell out. Black Friday and Cyber Monday follow in late November, but there is no guarantee a specific filament will be cheaper then.
Frequently Asked Questions
When do the Prime Big Deal Days filament deals end?
Amazon’s Prime Big Deal Days runs October 6 to 7, 2026, and the sale ends tonight, October 7, Pacific time. Many sale prices are for Prime members only.
What is the best filament for beginners?
PLA is the easiest to start with. The SUNLU Black PLA at $11.19 and the Creality Black & White 2-pack at $22.79 are the lowest-risk buys, since both are Amazon’s Choice with thousands of ratings. If you want color variety, the SUNLU 8-roll and Dynta 10-color bundles let you try many colors in small spools.
Should I choose PLA or PETG?
PLA is the easiest to print and suits most decor and everyday parts. PETG is listed as tougher with good layer adhesion, which suits functional parts, but it usually prints hotter and may need setting changes. Check your printer supports it before buying.
What is silk PLA and matte PLA?
Silk PLA has a shiny, metallic look, like the ERYONE Liquid Gold and the LOVOON tricolor. Matte PLA has a soft, non-glossy finish, like the ELEGOO pastel bundle. Both are for how the print looks, not for strength.
Do I need a filament storage box?
Filament absorbs moisture from the air, which can cause rough surfaces and stringing, and PETG and TPU are especially sensitive. A sealed box with desiccant and a humidity monitor, like the YOOPAI, helps keep a spool dry between prints.
Is a filament dryer better than a storage box?
They do different jobs. A storage box like the YOOPAI keeps a dry spool sealed with desiccant and a humidity monitor. A dryer like the SUNLU S2 heats the filament, up to 70°C, to remove moisture it has already absorbed, and the listing says it suits TPU, PLA, PETG and ABS.
Is a multicolor filament bundle worth it?
It is worth it if you want to try several colors, and the per-ounce price on the ANYCUBIC 10KG bundle is the lowest in this guide. The 250g bundles cost more per ounce, but they let you sample colors without buying 1kg of each.
Can prices change during the sale?
Yes. Amazon can change prices and availability at any time, and these prices were last updated on October 7, 2026. Always confirm the price on Amazon before you buy.
Final Word
Prime Big Deal Days ends tonight. Pick your material, compare the per-ounce price, and confirm the deal on Amazon before you buy. Stock can run out quickly on popular colors.
