Bambu Lab’s Halloween Sale Is the Biggest Filament Discount of the Year

Bambu Lab kicked off its 2026 Halloween Sale on September 28, and it runs until October 16 — which makes it the longest-running spooky-season promotion the company has ever put together. The headline number is up to 30% off, and unlike most seasonal sales, the deepest cuts are not on the flagship printers but on the thing every owner actually burns through: filament.

The timing is deliberate. The promotion overlaps Amazon’s Big Deal Days event on October 6–7, so several Bambu Lab machines and spool bundles show matching discounts on Amazon as well as on Bambu Lab’s own store. According to Tom’s Hardware, the sale period runs from September 28, 2026 (03:00 EDT) through October 16, 2026 (09:00 EDT), covering printers, filament, Maker’s Supply parts and the CyberBrick line.

Printer Deals: From $299 Entry Point to $250 Off the H2D

Bambu Lab’s flagship dual-nozzle machine takes the largest single dollar cut. The H2D with AMS combo drops from $1,999 to $1,749 — a $250 saving — while the same combo with the newer AMS 2 lands at $1,949. The standalone H2D falls from $1,749 to $1,549, and the large-volume H2S with AMS is discounted alongside it.

Down the range, the enclosed P1S — long the default recommendation for anyone printing engineering materials — is listed at $399, down from its $699 list price. The open-frame A1 is at $299, down from $399, and the A1 mini remains one of the cheapest credible ways into the ecosystem. A1 configurations bundled with the LED Lamp Kit are also showing up around $419.

Model	Sale Price	Reference Price
H2D + AMS Combo	$1,749	$1,999
H2D standalone	$1,549	$1,749
P1S (enclosed)	$399	$699
A1	$299	$399

Printers are only part of the story this year. Bambu Lab’s Halloween sale also bundles themed consumables, and TechRadar notes the sale covers themed bundles, Maker’s Supply and CyberBrick items, not just hardware.

Filament: The Discount Ladder That Actually Matters

For anyone running more than one printer, the consumables pricing is where the Halloween Sale earns its name. Bambu Lab is running a volume discount that scales with quantity: 5% off two items, climbing to a full 30% off at ten items or more. That ladder applies across the popular material lines:

• PLA Basic — the friendliest material for beginners and the workhorse for decor prints, landing at roughly $13.29 per 1 kg roll when you buy ten or more.
• PETG — for parts that need to survive weather, UV and knocks; the lowest price on the line is available at ten rolls.
• ABS — the impact-resistant, high-temperature material (the same family used for Lego bricks), also at its best sale price at ten items.
• CMYK lithophane bundle — cyan, yellow, magenta and jade white PLA spools for anyone who wants to print backlit photo panels and lanterns.

Ten rolls sounds like a lot until you price it out. Ten spools at 30% off is roughly the cost of seven — which is why farm operators and small print shops tend to treat this sale as annual stock-up rather than an impulse purchase. Filament also stores well if you keep it sealed with desiccant, so buying the year’s PLA in October is a straightforward way to cut per-part cost.

The Halloween Bundles: What’s Inside

Three themed kits are on sale, and they are unusually practical for seasonal printing rather than decorative filler:

• Pumpkin Family bundle — two PLA Basic spools (Pumpkin Orange and Bambu Green) plus an LED flame tea light, so you can print a jack-o’-lantern with real interior glow. US pricing is about $42.42 against a stated $48.97 value.
• Haunted House bundle — PLA Basic in black and jade white with an LED lamp kit, aimed at multi-part lit models.
• Glow/colour bundle — PLA Basic in Pumpkin Orange, PLA Glow in Green, and two PETG Basic rolls in black and white, which covers both spooky display prints and the structural parts that need PETG.

Maker’s Supply, Glow Filament and the R1 Laser

Beyond printers and filament, Creative Bloq reports up to 20% off Maker’s Supply Halloween specials, which is where the small parts live: LED modules, magnets, hardware kits and pre-made model components.

The other wildcard is the R1, Bambu Lab’s 55W CO₂ laser cutter and engraver launched on September 22, 2026. It is a separate machine rather than a printer module, and it handles wood, acrylic, leather, paper and fabric — engraving glass, stone and coated metals. For Halloween that means plywood pumpkin silhouettes, engraved acrylic window pieces and personalised treat tags that pair naturally with printed parts. If your Halloween plan involves a mix of plastic and wood, the R1 is the missing half of the workflow.

What’s Actually Worth Printing This Halloween

Discounts are only useful if you have a plan for them. The projects that sell and gift best in October fall into four groups:

1. Light-up decor — jack-o’-lanterns with tea light inserts, lithophane lanterns, and haunted house models. Print these in PLA and remember that thin walls and LED inserts beat candles for indoor safety.
2. Outdoor props — tombstones, signposts, spider webs and yard ornaments. Anything living outside should be PETG or ASA: PLA in direct sun and rain will sag and embrittle within a season.
3. Cosplay and masks — printed masks, armour plates, staffs and props. Print structural pieces in PETG or ABS for impact resistance, and keep costume pieces hollow with a 3–4 mm wall so they stay light enough to wear all night.
4. Figurines and collectibles — character figures, pet figurines of the family dog, and small gift pieces. These are exactly the objects people order rather than print themselves, which is where custom printing services come in.

Two practical notes from running printers at volume during a holiday crunch: batch your parts (a full plate of twenty small pumpkins costs far less machine time than twenty individual jobs), and keep a dedicated spool of glow green or glow orange loaded for anything that will be carried outdoors after dark — it doubles as a safety feature on trick-or-treat props.

Buy Now or Wait? A Quick Verdict

Two dates matter before you decide. The sale runs through October 16, and Amazon’s Big Deal Days lands on October 6–7 with overlapping discounts, so it is worth comparing both channels on the day you buy.

The H2D combo at $1,749 is a good-but-not-record price: TechRadar points out the same combo hit about $1,699 during Bambu Lab’s 4th Anniversary Sale in June/July 2026. If you specifically want the H2D, history says a sub-$1,700 window comes around again. If you are after an entry machine or consumables, the current numbers are the strongest of the second half of 2026 — the P1S at $399 and the A1 at $299 are near their floor, and nothing else in the calendar beats a 30% bulk filament discount.

Conclusion

Bambu Lab’s 2026 Halloween Sale runs from September 28 to October 16 with up to 30% off, a $250 cut on the H2D AMS Combo, the P1S at $399 and the A1 at $299. The best value is not the hardware, though — it is the filament discount ladder that reaches 30% at ten rolls, plus the themed bundles that ship the exact colours and LED parts you need for pumpkin and haunted-house prints. Buy filament in bulk, buy a printer only if these prices are near your target, and start printing before the last week of October — because every print farm on the internet has the same deadline as you.
